What are called 'public schools' in many of America's wealthy communities aren't really 'public' at all. In effect, they're private schools, whose tuition is hidden away in the purchase price of upscale homes there, and in the corresponding property taxes.
As public schools deteriorate, the upper-middle class and wealthy send their kids to private ones. As public pools and playgrounds decay, the better-off buy memberships in private tennis and swimming clubs. As public hospitals decline, the well-off pay premium rates for private care.
