It is happening. A good thing, indeed. Monopolies are bad policy, especially government monopolies. Monopolies do not respond to market demand.
However, I am an extremist. I do not believe in government education in any form. We did better before we had any of that. See John Adams and Abe Lincoln...
As I repeat ad nauseum, education cannot be "delivered." It can only be grabbed by those who wish to grab it. I also believe Harvard or Yale (your choice) diplomas should be an entitlement for all American kids on reaching age 21. Like the Wizard of Oz did.
Let's face it: How many Ivy grads know Fermat's last theorem, today? Or can translate Caesar or Plutarch? The education industry today is a giant rip-off and nothing more than a credential sales scam.
