(Taranto is the WSJ author who wrote the initial piece concerning the self-interest of suburban parents.)
"According to Taranto, parents who are wealthy enough to pick from among existing public school districts and private schools “already have” everything that a free educational marketplace could possibly offer them. That’s like saying upscale Soviet apparatchiks already enjoyed the benefits of capitalism because they could choose between a Lada and Yugo. The system of schools we have today is not a free market system. We have a legally protected 90 percent state monopoly school system with a small niche of non-profit schools mostly serving the religious education market due to the “free” government schools’ inability to serve that niche. This hobbled and distorted system no more captures the full panoply of options a true market would provide than the Yugo and Lada represented the full range of vehicle options in the capitalist West. Furthermore, no existing U.S. school choice program comes close to creating a genuine free market in education, as economist John Merrifield pointed out in a recent Cato Policy Analysis (“Dismal Science: The Shortcomings of U.S. School Choice Research and How to Address Them”).
Getting Americans to realize what they’re currently missing is indeed going to be a tough hurdle for school choice advocates. But it’s a hurdle that can be overcome."
UPDATE: Yet another interesting take on these concerns surrounding school choice, this time focusing on the cost issue. Studies have shown that unlike most government programs offering improvements, school choice is one that is not correlated with higher costs. The author of this response article indicates that this is the most effective way of convincing people to support school choice.
