Expensive, world-class facilities. When I was a kid, no school had a swim team because we didn't have pools. Can't put in a new school without state of the art gym, sports fields, often a pool. Giant auditoriums so your taxes can pay whack-job public speakers.
And for what? So kids can learn to read, write, and do math? We steal their childhoods from them so they can sit for 8+ hours per day and develop soul-crushing anxiety, so they have the chance to compete for a soulless career at a corporation?
Good riddance. Public school is a scourge on man kind.
