^Is there any other than controlled subsidies? All subsidies are controlled, that is part of the essence of a subsidy. The corruption that exists prior to K12 will still exist because K12 addresses the lacking in quantity of years of education rather than the root cause for the problem of education.
It is not evident as a whole because evidence shows that more private educated students edge public school students in almost any field of profession.... But there are extremely rare cases where an exceptional student from the public school can edge over private educated students... And yet, often times, if ever such an exceptional student is recognized, a scholarship for private education is offered.
The only way public schools can enhanced their education is through competition... competition against other schools for enrollment of students.
