Critics of tuition hikes say that private higher education has become a luxury that only Goldman Sachs bankers or Google employees with lucrative stock options can afford for their children. And high tuition costs aren’t only a concern of the rich. Public universities that have increased their tuitions over the last year include the University of California, the University of Washington and the University of Florida. Two years ago, Forbes showed that colleges have few incentives to cut costs. In that story, Alex Davidson wrote, "In the end, should students and parents just stop fretting over the high cost of elite universities and instead opt for a lower-priced public college? Probably. It turns out that where students go as undergraduates doesn’t help them earn more money over their lifetimes, according to a 2002 study by Stacy Dale, a researcher at Mathematica Policy Research in Princeton, N.J., and Alan Krueger, a Princeton economics and public affairs professor."
