The correct answer appeared in the radically leftist New York Times, of all places.

This is by Paul F. Campos, law professor at the radically leftist UC Boulder.

He writes:

[P]ublic investment in higher education in America is vastly larger today, in inflation-adjusted dollars, than it was during the supposed golden age of public funding in the 1960s. Such spending has increased at a much faster rate than government spending in general. For example, the military’s budget is about 1.8 times higher today than it was in 1960, while legislative appropriations to higher education are more than 10 times higher.

In other words, far from being caused by funding cuts, the astonishing rise in college tuition correlates closely with a huge increase in public subsidies for higher education. If over the past three decades car prices had gone up as fast as tuition, the average new car would cost more than $80,000.

Some of this increased spending in education has been driven by a sharp rise in the percentage of Americans who go to college. While the college-age population has not increased since the tail end of the baby boom, the percentage of the population enrolled in college has risen significantly, especially in the last 20 years. Enrollment in undergraduate, graduate and professional programs has increased by almost 50 percent since 1995. As a consequence, while state legislative appropriations for higher education have risen much faster than inflation, total state appropriations per student are somewhat lower than they were at their peak in 1990. (Appropriations per student are much higher now than they were in the 1960s and 1970s, when tuition was a small fraction of what it is today.)

As the baby boomers reached college age, state appropriations to higher education skyrocketed, increasing more than fourfold in today’s dollars, from $11.1 billion in 1960 to $48.2 billion in 1975. By 1980, state funding for higher education had increased a mind-boggling 390 percent in real terms over the previous 20 years. This tsunami of public money did not reduce tuition: quite the contrary.

[…]State appropriations reached a record inflation-adjusted high of $86.6 billion in 2009. They declined as a consequence of the Great Recession, but have since risen to $81 billion. And these totals do not include the enormous expansion of the federal Pell Grant program, which has grown, in today’s dollars, to $34.3 billion per year from $10.3 billion in 2000.

The more money that is attached to students, the more money universities charge – simple.

But where is the money going? Is it mostly going to research? To the classroom? To hire more and better professors?

No:

Interestingly, increased spending has not been going into the pockets of the typical professor. Salaries of full-time faculty members are, on average, barely higher than they were in 1970. Moreover, while 45 years ago 78 percent of college and university professors were full time, today half of postsecondary faculty members are lower-paid part-time employees, meaning that the average salaries of the people who do the teaching in American higher education are actually quite a bit lower than they were in 1970.

By contrast, a major factor driving increasing costs is the constant expansion of university administration. According to the Department of Education data, administrative positions at colleges and universities grew by 60 percent between 1993 and 2009, which Bloomberg reported was 10 times the rate of growth of tenured faculty positions.

Even more strikingly, an analysis by a professor at California Polytechnic University, Pomona, found that, while the total number of full-time faculty members in the C.S.U. system grew from 11,614 to 12,019 between 1975 and 2008, the total number of administrators grew from 3,800 to 12,183 — a 221 percent increase.

If you’re going to college or trade school, go to a low-cost school. Do a STEM degree or do a trade that pays well. Try to get tuition assistance even if it means going to a less prestigious school. And work at every opportunity you get in the most serious job you can find. Don’t spend your money – save it. Especially don’t spend your money on fun, vacations and alcohol. As soon as you grow up, you’re going to wish you could have it all back.
