Mark Perry of the University of Michigan has calculated, tuition for all universities, public and private, increased from 1978 to 2011 at an annual rate of 7.45%. By comparison, health-care costs increased by only 5.8%, and housing, notwithstanding the bubble, increased at 4.3%. Family incomes, on the other hand, barely kept up with the consumer-price index, which grew at an annual rate of 3.8%.
“Most of the growth in higher education costs, according to a 2010 study by the Goldwater Institute, a libertarian think tank, comes from administrative bloat, with administrative staff growing at more than twice the rate of instructional staff. At the University of Michigan, for example, there are 53% more administrators than faculty, and similar ratios can be found at other institutions.”
