More on rising cost of colleges and universities

In fact, public 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.

…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.

The rapid increase in college enrollment can be defended by intellectually respectable arguments. Even the explosion in administrative personnel is, at least in theory, defensible. On the other hand, there are no valid arguments to support the recent trend toward seven-figure salaries for high-ranking university administrators, unless one considers evidence-free assertions about "the market" to be intellectually rigorous.

What cannot be defended, however, is the claim that tuition has risen because public funding for higher education has been cut. Despite its ubiquity, this claim flies directly in the face of the facts.
