I have been trying for years to make people understand that a single system of government schools is fundamentally at odds with American values, especially individual liberty and equal treatment under the law. New York City Mayor Michael Bloomberg, in opposing a move to let city public schools close for Muslim holidays as they do for Christian and Jewish holidays, recently made my point in one, simple sentence:

One of the problems you have with a diverse city is that if you close the schools for every single holiday, there won’t be any school.

Exactly. So which religions, and which people, will get to be more equal than others, Mr. Mayor?

With universal school choice, we wouldn’t have to grapple with such terrible questions.
