The Debt Ratchet: How the System Turned Teachers into Interest Payments
Seventh in the series. Post 1 opened with the teacher: 1976 salary, no debt. Post 3 showed the machine that bought the publishers. This one closes the loop on the person standing in the classroom, because the final extraction does not run through the district budget. It runs through the teacher's own bank account.
Here is the teacher math. Two teachers, fifty years apart.
1976: a teacher with a bachelor's degree walks into a classroom. Salary: $12,005. Student debt: essentially zero, because college was affordable on a summer's wages and a part-time job. That teacher owns their paycheck from the first month.
2025: a teacher with a bachelor's degree and, increasingly, a master's degree (by 1991, 52.6 percent of teachers held one, up from 27 percent in 1971) walks into the same classroom. Salary: $61,600, which sounds like progress. The debt: graduate degree holders owe up to $102,790 in cumulative federal student loans, and 55 percent of master's degree holders carry federal debt (EducationData Initiative, 2026).
Same job. Same children. One owns their labor. The other is paying a subscription on it.
And the subscription is the point. Follow the money.
The tuition ratchet
In 1975-76, public four-year in-state tuition and fees cost $542 (NCES, Digest Table 330.10). In 2022-23: $9,750. That is eighteen times nominal.
Adjusted for inflation: $542 in 1975-76 dollars is about $2,581 in 2020-21 dollars. Against the actual 2020-21 price of $9,374, tuition has risen 3.63 times in real terms.
Now put the two series side by side, because they are the whole story. Teacher pay since the mid-1970s: up 7.7 percent in real terms (post 1). Public university tuition since the mid-1970s: up 263 percent in real terms. The credential that unlocks the pay lane got 3.6 times more expensive, and the pay lane itself rose 7.7 percent.
Run those numbers as a return on investment. The master's degree costs several times more real value than it did in 1976, and the raise it buys is nearly flat. No spreadsheet in any other industry survives that arithmetic. In education, the arithmetic is not supposed to work. The debt is the product.
Where the money came from
This did not happen by accident, and it did not happen in one step. It happened the way every ratchet happens, one click at a time:
1965: the Higher Education Act creates federal student lending.
1972: Sallie Mae, a secondary market for student loans. Student debt becomes a tradeable asset.
1978: the Middle Income Student Assistance Act opens borrowing to every income level.
1992: unsubsidized Stafford loans. Now you can borrow without demonstrating need. Need is no longer the gate. The gate is enrollment.
2006: Grad PLUS, uncapped graduate borrowing up to the full cost of attendance. The graduate degree, the exact credential teachers need for the pay bump, becomes infinitely financeable.
2010: Direct Lending. The federal government becomes the lender itself.
Each click widened the credit. Each widening let tuition rise to absorb it. Economists call the mechanism the Bennett hypothesis, after the education secretary who proposed it in 1987: federal aid enables tuition inflation. The evidence is debated, but the correlation is printed on the chart above: credit expands, tuition multiplies, and the two move together for fifty years.
The forgiveness fine print
The system's defense is forgiveness. Here is the fine print.
Teacher Loan Forgiveness: up to $17,500, after five consecutive years of full-time teaching in qualifying schools, on qualifying loans, initiated before the qualifying years ended. Since the program began, 10,100 teachers have ever received it. Total forgiven: $197.3 million.
Compare that to the federal portfolio: $1.724 trillion. Teacher Loan Forgiveness has relieved 0.011 percent of the total. It is not a program. It is a press release.
Public Service Loan Forgiveness: 3.3 percent of applications approved since inception. 3.72 million borrowers are eligible by employment; their average debt is $88,260. The documented failure mode is savage: borrowers enroll in repayment plans their servicers tell them qualify, pay for years, and get denied at application because the plan did not qualify after all.
The forgiveness is the marketing. The ratchet is the business model.
The parallel you already know
In post 3, we documented the leveraged buyout: a deal financed 50 to 90 percent with debt, collateralized by the target's own assets and future cash flows. The company pays for its own capture.
Student debt is the same structure with one improvement. It is 100 percent debt, collateralized by the borrower's future earnings, guaranteed by the federal government, and nondischargeable in bankruptcy. The student pays for their own capture, and the capture is serviced by every paycheck for the next twenty years.
In an LBO, the employees inherit the debt their new owners took on to buy them. In education, the student signs for it on day one. At least the LBO company gets a restructuring team.
The mechanism is identical because the money is identical: debt created today against futures that have not happened yet. The buyer borrows against the company's future. The student borrows against their own. Neither signs up to be collateral. Both are.
The exit
At Math Success, we did not build another credential. We built the thing the credentials were supposed to deliver: knowledge. Research-backed math instruction, printable materials, and teacher training that go directly to teachers and parents. No degree required. No six-figure prerequisite. The 40-plus years of research behind it came from classrooms, not loan offices.
One teacher who actually knows the math their students need is worth more than any credit-financed credential. That teacher can start tomorrow.
The system counts on you signing. Do the arithmetic first: the tuition, the interest, the forgiveness rates, the pay. Then decide who the debt serves.
Do the math. Follow the money.
