Quote from Andrew J. Coulson,
"In education markets, like the Asian tutoring industry, top teachers are superstars who get to design curricula for thousands or even millions of students and train scores or hundreds of other teachers to use their effective methods. Quality providers expand and are emulated by competitors, and there is a powerful incentive for meaningful innovation. ... One teacher in Korea’s private tutoring sector made $2 million last year because his web-based employer has profit sharing and he’s brilliant at what he does, so he gets tons of students. That’s what should have happened to [Jaime] Escalante. That’s the sort of success that should greet excellence in education at all levels. It doesn’t because we don’t have a market."
