WASHINGTON

MUCH is being written about the preposterously high cost of college. The median inflation-adjusted household income fell by 7 percent between 2006 and 2011, while the average real tuition at public four-year colleges increased over that period by over 18 percent. Meanwhile, the average tuition for just one year at a four-year private university in 2011 was almost $33,000, according to the National Center for Education Statistics. College tuition has increased at twice the rate of health care costs over the past 25 years.

Ballooning student loan debt, an impending college bubble, and a return on the bachelor’s degree that is flat or falling: all these things scream out for entrepreneurial solutions.

One idea gaining currency is the $10,000 college degree — the so-called 10K-B.A. — which apparently was inspired by a challenge to educators from Bill Gates, and has recently led to efforts to make it a reality by governors in Texas, Florida and Wisconsin, as well as by a state assemblyman in California.

Most 10K-B.A. proposals rethink the costliest part of higher education — the traditional classroom teaching. Predictably, this means a reliance on online and distance-learning alternatives. And just as predictably, this has stimulated antibodies to unconventional modes of learning. Some critics see it as an invitation to charlatans and diploma mills. Even supporters often suggest that this is just an idea to give poor people marginally better life opportunities.
