A study from the American Institutes of Research finds that federal and state governments have wasted billions of dollars on subsidies for students who didn’t make it past their first year in college. The federal total for first-year college drop outs was $1.5 billion from 2003 to 2008.

Due to data limitations, the figures are only for first year, full-time students at four-year colleges and universities. Community colleges have even higher drop-out rates, and part-time students or students returning to college are more likely to drop out. Therefore, the numbers in the report are “only a fraction of the total costs of first-year attrition the nation and the states face.” Moreover, it doesn’t include the cost for students who drop out some time after their sophomore year.

Federal policymakers from both parties are fond of lavishing subsidies on college students. Proponents argue that without federal subsidies, an insufficient number of future workers will possess the skills necessary to compete in a global economy.

However, a Cato essay on federal higher education subsidies argues that students wishing to attend college already have plenty of incentive to save or borrow from private sources:

Supporters of student aid subsidies argue that higher education is a “public good” that would be underprovided in a free market. However, that is probably not the case. People have a strong incentive to invest in their own education because it will lead to higher earnings. Those with a college degree will earn, on average, 75 percent more during their lifetime than those with just high-school degrees. That is a big incentive for people to save or borrow in private markets to pay for their own college costs. There is no “market failure” here.

In fact, higher education subsidies drive up tuition prices:

It is matter of supply and demand. More and more Americans have sought a college education, which has pushed prices higher. Ordinarily, such upward pressure would be restrained by consumers’ willingness and ability to pay, but as government subsidies have helped absorb tuition increases, the public’s budget constraint has been lifted. Peter Wood, a professor at Boston University noted that federal subsidies “are seen by colleges and universities as money that is there for the taking … tuition is set high enough to capture those funds and whatever else we think can be extracted from parents.”

But isn’t it great that Uncle Sam is helping put more young folks in college? Not necessarily:

Many of those additional students may not have been ready, or suited, for college. As evidenced by the rising shares of college students who require remedial work. Further evidence of the problem is that institutions have lowered their standards to adapt to the rise in second-rate students. The American Academy of Arts and Sciences reported that from the mid-1960s to the mid-1990s, college grade point averages grew steadily but Scholastic Aptitude Test scores declined. The share of entering college students who complete degrees has also fallen over the decades. In addition, while college attendance is up, overall adult literacy has barely budged over the last 15 years.

The essay also notes that college students devote 3.2 hours to education on an average weekday, versus 3.9 hours to “leisure and sports,” and that the six-year graduation rate for bachelor’s students is only about 56 percent, indicating that many students are not very serious about education.

Just as housing subsidies incentivized people to purchase homes that they otherwise shouldn’t have, higher education subsidies have incentivized people to go to college who weren’t ready or suited for it. In both cases, the cost to taxpayers has been substantial while the alleged benefits have proven illusory.
