European children are reported to have higher academic achievement (math, english, science, art, music) than US kids.
Do you think that perhaps that is because, in almost all of Europe, the money is attached to the child - parents decide which school the children should go to. If parents believe their child to be musically inclined, they send the school that emphasizes music (or art, or science/math, etc.)
In other words ... vouchers are the solution.
It depends: Yes and No
Yes, vouchers will be the solution if they can be a means to building a private infrastructure.
Yes, vouchers may be a solution if the direction is toward parents taking more and more responsibility for paying for their own children's education and moving toward eventual separation of school and state.
No, voucher will not be a solution if strings are attached making private schools into government controlled schools.
No, vouchers will not be a solution if they lead to tuition inflation as has happened with college student loans and Pell Grants.
