A lot of parents start worrying about paying for college education soon after their child is born. After that, there's the stressful process of applying to colleges, and then, for those lucky enough to get admitted into a good college, there's college debt.

But author Kevin Carey argues that those problems might be overcome in the future with online higher education. Carey directs the Education Policy Program at the New America Foundation. In his new book, The End of College: Creating the Future of Learning and the University of Everywhere, Carey envisions a future in which "the idea of 'admission' to college will become an anachronism, because the University of Everywhere will be open to everyone" and "educational resources that have been scarce and expensive for centuries will be abundant and free."
