Won't that create huge waiting lists for the better performing schools? How will it improve the poorer schools? Won't they need lots of money to hire the more 'successful' and 'better performing' teachers/administrators? How would this practically make a kid learn e.g. mathematics or physics better?
*sigh*
I am not an economist, but this makes even me, with my very limited knowledge of economics, cringe.
There won't be huge waiting lists for the better schools because there will be no artificial restriction on supply, as there is now. What works will be adopted by everyone who wants to remain competitive. Those who don't will die out.
It will improve the poorer schools by either forcing them to adopt what works, or driving them out of business due to competitors taking their place, and offering better service.
They won't need a lot of money to hire the better teachers and admins because there won't be such a shortage of teachers/admins once the voucher system comes into place. First, because they will cut most of the pork and crap if it hindering academic performance. A school will build up a reputation for good academics first, and invest in playgrounds and stuff only later. Secondly, because more people will want to be teachers, as they will get better pay under this system , because of the nature of vouchers (vouchers are a much more efficient system, as the private school has no incentive to waste a single cent on bureaucratic overhead - thus the same money invested in vouchers will get us a significantly better return in terms of schooling).
Secondly, once teaching is shorn of most of the bullcrap baggage which it has now, and teachers' salaries become competitive, a better quality of people will choose to enter the profession.
This would make children learn mathematics and physics better because they will choose to go the the schools which can teach them better. Now that they have a choice, they will choose the school which works instead of that which doesn't, but which they are violently coerced into paying for. The ones which don't teach them properly will be outcompeted by those that do. That is how quality will improve.
All these problems you have enumerated exist in a framework with an assumption of an artificial restriction on supply (as there is now).
