Conservatives routinely (and correctly) chide liberals for misunderstanding the law of unintended consequences. One positive policy will lead to unanticipated negatives outcomes. For instance, it made sense to focus welfare on single mothers, since they’re the neediest. But that accidentally created an economic incentive for people not to get married.
Here’s a conservative social policy with an unintended consequence. For years, conservatives, and more recently liberals, have proposed charter schools to shake up and improve the public schools. The Wall Street Journal reports that one consequence is that Catholic, or parochial, schools are suffering.
