Did Obama choose America's worst school?

Greg Forster is perplexed that Mr. and Mrs. Obama would pick Sidwell Friends, a "shockingly substandard school" (no unionized workforce, no collective bargaining, weak teacher benefits, and so on), "even though they had the opportunity to go with the nation's most lavishly funded and heavily unionized schools."

As patriotic Americans, how can we stand by while our president's family gets such substandard services?
