Doubling the teacher salaries and cutting the number of students in each class to below 25 are great ideas. They, however, are very expensive. But if you have competition and differential payment to teachers you can pay those teachers that you really want high salaries without destroying the economy on prohibitively expensive salariies.

your claim that only rich people will be able to participate in the competition is complete non-sense. Look at the Catholic schools in the US and at the Haredi schools here in Israel. Competition simply gives more efficiency for your dollars.
