I think a compelling case can be made, but we need an educational campaign to make the case better known. We also need to be able to demonstrate the value of educational choice in practice. In addition to choice opponents who simply fear the unknown, there are other choice opponents who know full well what choice would mean, and they don't like it. But such objections are to be expected from any group that is narrowly interested in its own welfare, receives huge subsidies from taxpayers, and is subject to little accountability. From a consumer point of view, Toyotas and Mazdas were the best things that ever happened to General Motors and Ford.
Competition is the key if consumers are going to get the best possible product.
That holds true in education, too. Similarly, the presence of successful private schools in a community will increase the effectiveness of public schools. The public schools will be forced to compete with private schools. In the beginning, those private schools will generally beat the public schools on both results and costs. But there are many things the public schools can do to improve their performance.
