A higher-ed bubble even bigger than student loans - Sharon Epperson, CNBC

There are growing concerns that the benefits of a college degree are on the decline, while costs continue to rise. This so-called bubble in U.S. higher education is focused on the mounting debt load of college students and their difficulty in finding a degree or job that economically justifies the cost. But in the next 25 years, some futurists say the bigger issue—and the one that could likely cause this bubble to burst—will be the inevitable collapse of many colleges and universities as learning goes virtual. Clayton Christensen, a professor at Harvard Business School and the father of disruptive innovation theory, famously predicted in 2008 that half of high school classes will be online by 2019. With the expansion of the digital campus, many mid-level institutions of higher education could become obsolete, and the new landscape may be largely unrecognizable. http://www.cnbc.com/id/101985258
