Discussing the likelihood that the Obamas will put their kids in private schools (and asking whether they will make this option easier for other Americans by supporting school choice), University of Michigan economist Mark Perry points out, at his excellent blog Carpe Diem, the extent to which teachers are voting with their feet by putting their own kids in private schools:
This is not a new discovery. Data has shown this for years. The chart shows that a much greater percentage of school teachers put their children in private schools than do the general public. In other words, the people who know most about public schools seem to be the least likely to put their own children there.
