What explains the high, and rising, cost of college in the U.S.?
KARL ULRICH: Higher education does not have to be costly. Utah Valley University, a fast-growing school with an enrollment of more than 30,000, educates students for about $8,000 per year. That’s one third less than the average cost of educating a high-school student in the U.S.
Most of the noise about the cost of higher education surrounds the flagship state universities and the elite private institutions. Those schools are very costly. For instance, Haverford College, where my son is a student, spends $68,000 per year for each of its students. (Note that the average student pays less than $30,000 at Haverford because of financial aid.)
