Privilege retreats. That’s the first thing to understand about it: it doesn’t just stand still, waiting for everyone else to catch up, but keeps moving. Sneak past the velvet rope keeping the great unwashed out of the party, and another rope will materialise behind it, guarding an even more exclusive gathering. Level a playing field, and soon the lucky few start getting invites to play in another more exclusive game. The good stuff always seems to be just out of reach.
