Barack and Michelle Obama have decided to send their daughters to the Sidwell Friends School, an historic private school in the District of Columbia, started in 1883 by the Quakers. It provides a high-quality high school education and also has the kind of principles and values that the Obamas support.
I believe that private education has always been an integral part of our educational system in America. As long as private and religious schools make sure that they are serving the less affluent sectors of our society by providing scholarship help for worthy, less affluent students, then they are serving the broader goals of our society and should play an important role in the United States, without criticism from the left. Not everyone has to go to a public, state-supported school (my kids did, by the way).
