I just fired off this letter to the editors of the Houston Chronicle:

Who Is Really “Obsessed” Here?

In an August 16 editorial (“Voucher Obsession”), you claim as fact that “vouchers would only [help] a few students.” The Netherlands has had a nationwide public and private school choice program since 1917. About three quarters of Dutch students now attend private schools. Chile introduced school choice in the 1980s, and the majority of students in that country are now enrolled in private schools.

As school choice programs allow demand to rise, the supply of private schools rises to meet it. For you to be unaware of such an elementary fact about market-based education systems does a disservice to your readers. And it begs a serious question: if you know so little about school choice, why do you oppose it so obsessively?
