Steve Jobs had done pretty well with the "young, idealist people working for [relatively] pennies" model. But is there no value to experience in the teaching profession?
There is absolutely value. But that value is currently minimized with the current system. Jobs may be talking about young idealistic people starting schools, but he says nothing to imply that you wouldn't want experienced, motivated teachers at those schools doing the actual teaching. It's like a business person starting a tech startup and getting the best developers he/she can find. I think the same strategy would apply here. Experienced teachers would certainly increase the likelihood of success, as long as those teachers also had an open mind and were willing to do things differently than they were used to.
