When my dad was in high school, in the 1940s,
it was mostly the children of snooty WASP country-club types who could afford to go to Harvard or Yale. Not some very bright black kid from Detroit or some very bright coal miner's kid from West Virginia, or some poor Jewish kid from the Bronx.
For all its faults, higher education in the U.S. has become democratized. Ivy League universities are no longer limited to America's elite WASP families.
