Mowing Lawns and Flipping Burgers Used to Fund Four Years of College. What Changed?

The Math That Used to Work

It's a story your parents or grandparents might have told you: "I worked summers at the grocery store, saved my paychecks, and paid my way through college." For millions of Americans in the 1970s and early 1980s, this wasn't a humble brag—it was just how things worked.

In 1975, the average in-state tuition at a public university ran about $1,300 per year. The federal minimum wage was $2.10 an hour. A determined teenager working full-time (40 hours a week) for a 12-week summer would gross roughly $1,000 before taxes. Add a part-time job during the school year, a modest scholarship, or some parental help, and you had a plausible path to a four-year degree without borrowing a single dollar.

The arithmetic was tight, but it was possible. More importantly, it was expected. A summer job wasn't just pocket money for entertainment—it was a down payment on your future.

The Divergence Begins

Now let's look at 2024. The federal minimum wage has climbed to $7.25 an hour—a 245% increase from 1975. Sounds impressive until you check the other number: average in-state tuition at a public university now sits around $9,750 per year. That's a 650% increase.

The same summer job today—full-time at minimum wage for 12 weeks—nets roughly $3,480 before taxes. After taxes, a teenager might pocket $2,900. That covers roughly 30% of one year's tuition. A decade ago, it covered nearly 80%. Two decades ago, it was essentially a full ride.

But the story gets worse when you factor in what economists call "real purchasing power." When you adjust both the 1975 wage and the 2024 wage for inflation, the divergence becomes even starker. A 1975 summer minimum-wage job was worth roughly $11,000 in today's dollars—more than enough to cover tuition and room and board combined. Today's minimum wage job, in real terms, is worth less than it was half a century ago.

What the Data Actually Shows

The College Board has tracked this gap with precision. In 1975, a student working a summer job could realistically pay for 100% of in-state tuition and about 60% of living expenses. By 2000, that ratio had shifted to roughly 50% of tuition and 20% of living expenses. Today, it's closer to 25% of tuition and nearly nothing beyond that.

This isn't about teenagers becoming lazier or less motivated. It's about the math breaking down entirely.

Consider what else has changed: housing costs near college campuses have tripled relative to wages. Textbook prices have quintupled. Dorm fees, meal plans, parking permits, technology fees—these didn't exist in 1975, or they cost pennies. Meanwhile, the minimum wage has barely budged since 2009. Adjusted for inflation, it's actually worth less than it was 15 years ago.

The Invisible Consequence

This isn't just a financial story. It's a story about what happens when a generation loses access to a path that once existed.

For a teenager in 1980, a summer job represented agency. It meant you could contribute meaningfully to your own education. You had skin in the game. You understood sacrifice and delayed gratification because you'd earned the money yourself. That job also kept you connected to your community—you worked at the local pool, or the hardware store, or the restaurant where your parents ate.

Today's teenagers face a different equation. A summer job still provides valuable experience and some money, but it can't realistically fund college. The gap is too wide. So families who want their children to attend university without crushing debt must either save aggressively for 18 years, qualify for need-based aid, or take out loans. Those are the only three doors that remain.

This shift has had profound downstream effects. Student loan debt has exploded from $5.8 billion in 1993 to over $1.7 trillion today. The average student borrower graduates with $37,000 in debt. That debt delays homeownership, marriage, and childbearing by years. It narrows the choices available to young adults—you can't take a lower-paying job in public service or the arts if you're carrying $40,000 in loans.

Why the Math Broke

The answer isn't a mystery. College costs have risen faster than inflation, driven by decreased state funding, increased administrative bloat, and an arms race in campus amenities. Wages have stagnated, kept down by policy choices and labor market dynamics. The two lines on the graph have been moving in opposite directions for 40 years.

Some of this reflects genuine improvements: colleges are safer, more inclusive, and offer more sophisticated facilities than they did in 1975. Some of it reflects pure inflation outpacing wage growth—a pattern that has reshaped American economics broadly.

But the result is unambiguous: the summer-job-as-tuition-funding model is extinct. It survives now only in nostalgia and in the advice of parents who don't realize the math has fundamentally changed.

What Comes Next

There's no easy fix to this problem. Raising the minimum wage would help, but it would need to rise dramatically—and stay ahead of college cost increases—to truly restore the old equation. Reducing college costs would also help, but that would require reversing decades of structural decisions about how universities fund themselves.

For now, the summer job remains valuable—it teaches work ethic, provides experience, and generates some income. But it no longer functions as the pathway it once did. That matters, not just economically but culturally. It means one fewer way for a young American to bootstrap themselves toward independence.

Your grandparents' story—work, save, graduate debt-free—isn't impossible anymore. It's just impossible for most people. And that's a historical shift worth understanding.
