A Fix for Credit Card, Student Loans, and Mortgage Debt

IMPORTANT NOTICE:

I am not advocating anyone take current 0% interest loans or credit offers. These products exist, interest rates can change, fees can be added, and penalties can accumulate in ways that trap people in long-term debt.

In this article, I discuss an idea for systemic change to how credit works and what a truly 0% interest credit system could look like. These ideas only make sense as part of a broader structural change where interest rates cannot be raised, fees cannot be added for late payments or for default, and the rules are different from today.

In this article and the audio episode that accompanies it, I lay out a practical alternative: Credit as Earned Reputation (CER), not as borrowed money. For most of human history, credit worked as trust. Modern finance replaced that with interest, leverage, and bailouts,  disconnecting credit from accountability, and turning everyday borrowing into a trap. I explore a realistic, non-utopian model, in which there is no interest on loans for:

• Student loans
• Credit cards
• Mortgages
• Why this approach doesn’t break the bank
• How it outperforms today’s model for loans

It isn’t about free money. It’s about rebuilding the credit system so borrowing leads to stability, not extraction. This episode explains what Credit as Reputation is, and how it could work to make it easier, faster, and fairer to re-pay loans.

Reputation as Credit: A Practical Solution to Inflation, Inequality, and Debt Traps

When you take out a loan - for a home, credit card, or student loan for example —the bank does not give you money or loan money it has. The money doesn’t come from what economist call “loanable funds.” Money is created as your loan is made. With a credit card example, the Federal Reserve banking law is called “Monetizing your signature.” Your signature is turned in to cash - well - as a loan on the accounting books. For how this is done and the accounting that happens, listen to my interview with economist, Steve keen.

This episode is about a solution that plagues many, a solution to credit card debt, inflation, and housing prices. It’s a solution to the cost of higher education and the quality of education at colleges and at universities. The solution is simple- unless a bank uses loanable funds when it gives a loan - it’s the borrower’s  credit with which the money for the loan is created. A borrower, therefore, should not be charged interest on such a loan.

The proposed system: Credit as Earned Reputation (CER)

The core principle is credit should behave as reputation: earned slowly, lost quickly, expanded by repayment, and restricted by failure. There should not be compounding interest on credit, as banks are not lending pre-existing money the way most imagine.

The Proposed Rules:

1. Credit is the person’s asset, not the bank’s
2. No interest on the loan.
3. Banks can charge transparent, finite fees for administration and payment processing
4. As a loan is repaid, credit expands
5. If payments are missed, credit contracts
6. In the event of a default, credit disappears until the principal is repaid

Example 1: A Student loan

In a workable version of the CER model there is 0% interest on principal (debt doesn’t grow while repaying). There are credit-based caps, limits tied to completion and repayment outcomes.. The loan may be set up to enable automatic income-based repayment from the start. A requirement may be for schools to share some of the risk. Programs with poor repayment outcomes could lose access to credit. The result is students repay what they borrowed — no more. Defaults decline as repayment becomes possible, and low-quality school programs stop being profitable.

Example 2: Credit cards

Today’s failure models are 20–30% APR, revolving credit traps, and incentives that reward keeping people indebted.  In The Reputation as Credit model, there is 0% interest, revolving credit, and only one hard revolving limit per person, not per card. If the card is maxed out, no new revolving credit can be obtained anywhere (unless the bank or loan is made using loanable funds) until it is repaid. Under this model, repayment restores access to credit; missed payments shrink future a credit, and a default blocks access until the principal is repaid.

Banks earn income through interchange (merchant-paid fees), flat service fees, and late fees which are non-compounding. This shifts “discipline” from punishment to reality. Repayment is now an incentive, a practical and achievable one.

This model does not propose eliminating banks, banning interest everywhere, or “free money.” Banks can process payments, administer accounts, and earn fees. They don’t get to trap households in compounding loops, profit endlessly from money created with credit, and privatize the upside while offloading systemic losses when loans default and banks fail.

Potential Opposition Arguments

“People will default strategically.”

Defaults happen today. The alternate system makes defaults less attractive as it destroys future access across the entire revolving lane of credit — transparently.

“Who pays for losses?”

In economics, this is called loss absorption - the effect on banks and society when someone or a corporation or a bank defaults. Losses exist today. The difference is today, losses are absorbed after maximum interest is extracted from the borrower. In my model: losses are absorbed once, at the amount of the principal, transparently. Because repayment is easier, defaults are less likely.

More Examples

The following example are for each buying a home, a student loan, and a credit card. We’ll compare the effects for if loan is paid off to if the borrower defaults, the effects on the borrower, the bank, and on society.

Home mortgage Loans

Assumptions (same for both):

• Home price: $400,000
• Down payment: $80,000
• Loan principal: $320,000
• Term: 30 years
• For comparison purposes, a market interest rate of 6.5%

A) Today’s System (Interest-based mortgage) with no loan default

Borrower experience:

• Monthly payment ≈ $2,020
• Total paid over 30 years ≈ $727,000
• Interest paid ≈ $407,000
  (More than the original house price)

Effect on the borrower:

Monthly cash flow is tightly constrained. A large share of income goes to non-productive interest. The person experiences a slower accumulation wealth, ie savings for 401K and other expenses. There is a a higher sensitivity to job loss and rate changes. Most people must borrow a larger principal to afford inflated prices. Even when everything goes “right,” the borrower pays twice for the same house, and carries decades of financial fragility with little margin for shocks.

The Bank’s experience:

Interest is a long-term, predictable income for banks. Mortgages are an income-producing asset for them. The incentive for banks is to maximize the loan size, extend the duration of the loan, and keep asset (home prices) prices high. Banks do not need borrowers to thrive — they need, quite literally, borrowers to remain indebted. The interest on loans pays their salaries.

Societal effects:

Housing prices: Interest expands to “what buyers can pay.” Prices rise to absorb the capacity of monthly-payments. The purpose of housing becomes that of a financial asset first, shelter second.

Inflation: Asset inflation (homes, land) outpaces wage growth. The Consumer Price Index (CPI) understates lived inflation. Rent follows home prices upward.

Economic behavior: People delay families, mobility, risk-taking. Credit dependence increases. System becomes fragile to interest rate changes. Even without defaults, the current system, extracts hundreds of thousands of dollars per household, inflates asset prices, increases inequality, and embeds instability.

B)  Credit as Earned Reputation (CER)
Same Home Mortgage, 0% interest, no default by the borrower

Borrower experience

• Monthly payment ≈ $890
• Total paid over time = $320,000
• Interest paid = $0

Effects on the borrower

Cash flow improves immediately. The home buyer experiences a faster path to ownership, with greater resilience to shocks in interest rates and housing availability. Credit access depends on their behavior, not the size of the  balance. Borrowers still have skin in the game. While missed payments reduce future access to credit, reputation governs access, not compounding interest and penalties.

Bank’s experience

There is no interest income from mortgages. Bank earn their money via origination fees, servicing fees, and reputation-based access pricing. Banks must underwrite for repayment ability, not asset appreciation, care about borrower success. Speculative lending becomes unattractive. Banks remain solvent,  and  less extractive.

Societal effects

Housing prices: Buyers can no longer “capitalize interest.” Maximum bids fall. Home prices normalize toward construction cost, land value, and local incomes, with a reduced speculative demand.

Inflation: Asset inflation slows dramatically. Less money creation is tied to compounding debt. Housing stops acting as an inflation engine. CPI aligns closer with lived costs. People regain mobility. Risk-taking becomes productive, not desperate. Debt no longer dictates life choices. Fewer bubbles form.

Side-by-side Comparison

Even when no one defaults, interest-based credit inflates asset prices, extracts value continuously, and destabilizes the system. The CER model does not rely on people failing less. It relies on truth: Credit is governed by access. Interest disguises extraction as necessity.
 

Examples Showing Effects of Home Mortgage Loans with Defaults

Assumptions (typical case)

• Home purchase price: $400,000
• Down payment: $80,000 (20%)
• Loan principal: $320,000
• Term: 30 years
• Interest rate: 6.5% (historically normal)

Example A: Mortgage default (in today’s system)

Person borrows $320,000 to buy a home. They make payments for several years. Then something happens, and they fall behind: a job loss, medical crisis, divorce, or regional downturn.

What happens 

Interest continues accruing on the unpaid balance, late fees stack up, and penalty interest apply. Legal fees may be added during foreclosures. Even if the borrower stops paying, the debt keeps growing. Typical outcome: Foreclosure begins. The home is seized and sold, often below market value. The remaining balance after sale may still be $40,000–$100,000. The borrower may face deficiency judgments, wage garnishment, and tax consequences. Home is lost. Credit is destroyed for 7–10 years. Cannot qualify for a mortgage again for many years. Often forced into higher-cost rentals. Financial recovery becomes mathematically harder.

Result for the lender

The lender has already collected interest as income. Loss partially covered by foreclosure proceeds, insurance, and the resale of distressed assets. The principal didn’t fully come back. The borrower lost the home and future credit. This already happens.

Example B: Mortgage default — CER 0%-interest system

Person borrows $320,000 to buy a home. Same life event. Same inability to pay.

• No interest accrues. There are no compounding penalties.
• Credit access is shut off
• Balance stays $320,000 minus whatever has been repaid

Resolution paths

The home is sold. Sale proceeds reduce principal directly. No ballooning debt. No residual interest traps Payment resumes only when income recovers. Credit remains unavailable until repayment resumes. Walk-away outcome: Credit remains inaccessible. No exploding debt tail follows them for decades.

Result for the borrower

The home is lost, with the same consequences. Credit access lost, without exponential debt growth. Recovery remains possible within their lifetime.

Result for the system

Failure is acknowledged early. Risk is visible. Losses are real but contained. No illusion of “solvency” created by compounding interest.

The CER system does not introduce a new failure mode- It removes the compounding penalty layer that worsens an existing one.

Credit Cards

Example: Credit Card with Default (in today’s system)

• Person borrows $5,000
• Lose a job, get sick, or misjudge finances
• Stop paying

What happens today:

1. Interest continues to accrue, and fees stack up.
2. The balance balloons to $8,000–$12,000.
3. Eventually, the account is charged off, credit is destroyed, and the lender sells the debt for pennies. The borrower still cannot use credit.
4. The lender already collected interest as income, priced in the default, and may get partial recovery from a sale or tax offset.

The same example in CER system

• Person borrows $5,000
• They default

What happens:

1. No interest accrues
2. Balance stays at $5,000
3. Credit access is shut off immediately. The person cannot use credit again and must repay principal to restore access or live without credit.

The CER system does not introduce a new failure mode.  It removes the compounding penalty layer that worsens an existing one. If I don’t pay back my credit, that presupposes I never need to use credit again. That already happens.

Default already means no credit, years of penalty, and worse outcomes. My system simply says: failure has consequences, not exponential ones, ones that make recovery mathematically impossible.

What Critics Don't Understand

Critics of a 0% interest system with rules as I’ve set out, implicitly assume interest = discipline, and punishment = responsibility. In reality, access is the discipline, repayment is the incentive, and interest is the trap. We’re swapping a behavior-based enforcement mechanism for a price-based punishment mechanism. It’s a better design.

People warn that someone won’t repay and principal will be lost. That already happens. Today, when people default, they lose access to credit and the lender eventually absorbs the loss — after extracting as much interest as possible from them and making the problem worse.

The CER system doesn’t add a new risk; it removes the compounding penalties that increase defaults. The difference is that failure stays finite, and repayment becomes achievable.”

That’s not ideology. That’s comparative reasoning. My model doesn’t deny risk. It reduces failure cascades. Any serious system designer should prefer fewer defaults, smaller losses, a faster recovery, and clearer accountability.

Studen Loans

Here’s a side-by-side examples for student loans, using the same student, same tuition cost, under the two systems.

Assumptions for all scenarios

• Degree cost financed by loans: $60,000
• Term: 20 years
• Interest rate 6.8%
• Student graduates and earns a modest middle-income wage

A) Today's System - Full Repayment 

Student experience

• Monthly payment ≈ $460
• Total paid ≈ $110,000
• Interest paid ≈ $50,000

Effects on the student

Starts adult life with heavy fixed payments. Delays home ownership, family formation, and risk-taking (business, relocation). Education becomes a long-term financial drag, not a launchpad. Credit score is “good,” but cash flow is weak. Even when the student “does everything right” they pay almost double for the same education.

Bank experience

Loan produces predictable, compounding income. Risk is partially backstopped by the government. Incentive to raise tuition ceilings and expand lending volume. Little pressure to care whether education actually improves outcomes. Banks are paid because the student remains indebted, not because education succeeded.

Societal effects

Education pricing: Interest expands “ability to pay.. Tuition rises faster than wages. Colleges capture the excess. Economic behavior: Young adults remain credit-constrained. Lower household formation. Slower entrepreneurship. More fragile labor force. Inflation: Education costs inflate structurally. Debt grows faster than productive capacity.

B) CER, 0% Interest,  Full Repayment

Student experience

• Monthly payment ≈ $250
• Total paid = $60,000
• Interest paid = $0

Education behaves like a delayed earnings investment, not a lifetime tax. Faster financial independence. Credit access expands with repayment behavior. Much lower stress and default risk. The student pays for what they received and keeps future options open.

Bank experience

No interest income .Revenue via origination fees and servicing fees.Incentives are to fund education that leads to repayment, and pressure schools to share downside risk. Bad degrees become harder to finance. Lenders now care whether education works.

Societal effects

Education pricing: Tuition ceilings stop inflating. Schools forced to justify costs. Fewer predatory or low-ROI programs. Economic behavior: Earlier household formation. More mobility and entrepreneurship. Stronger middle-class formation. Inflation: Education stops acting as a cost escalator. Debt growth slows relative to wages.

PART II — Student Loan, with Default

The same student. But life happens.

Today's System with Student Loan Default

Student experience

• Original loan: $60,000
• Payments missed
• Balance grows to $90k–$120k
• Fees, penalties, capitalization

Their credit is destroyed. Wages may be garnished, tax refunds seized. The loan often cannot be discharged. They cannot reset their life. The student is punished forever.

Bank / lender experience

Interest already booked as income. Default priced into portfolio. Government guarantees soften losses. Loan may be sold or offset. The principal often does not come back. The system already extracted value.

Societal effects

Long-term underemployment, suppressed consumption, higher mental health burden, and Education turns into a social trap. This already happens at scale.

Credit as Earned Reputation (CER) System ( 0% Interest), Student Loan Default

Student experience

• Loan balance remains $60,000
• No interest accrues
• Credit access immediately shut off
• Cannot use new credit. Must repay principal to restore access or lives without credit
• Failure has consequences — recoverable ones

Bank experience

No interest income is booked. Loss is transparent. The incentive becomes:

• improve underwriting
• pressure schools to co-finance
• avoid over-lending
• Share responsibility for outcomes.

Societal effects

Fewer lifelong debt prisoners. Faster reintegration into productivity. Lower administrative and legal costs. Education failures don’t metastasize

Side-by-side Summary (Student Loan)

The critical insight

Default is already the end of credit. Interest doesn’t enforce responsibility, it enforces permanent damage. The CER system does not create a new moral hazard - It removes a mathematical one. It says responsibility matters, repayment matters and failure has consequences, but recovery remains possible. Sated plainly, education should test intelligence, not trap it.

Interest made sense when lenders risked their own capital and bore full losses. In a system where money is created through credit and losses are often socialized, interest has become rent on trust rather than compensation for sacrifice. The CER proposal is to realign credit with accountability.

Money is created when loans are created. Banks decide who gets access. That’s why inflation and asset booms benefit some and punish others. The CER alternative is simple: treat credit as what it is — reputation. Credit expands with repayment and disappears with default. No compounding interest traps. Banks can still charge transparent fees - they can’t rent trust.

This isn’t utopian. It’s a credit lane that restores accountability, reduces defaults, and makes the system fairer without breaking it.
