You eventually get there: the US blows a ton of cash on private education, but our public education expenditures -- which this thread has been about up to now -- are unexceptional compared to peer nations. Smack-dab in the middle of the usually pack, really. (And we're also a far less dense country than many of the countries we technically out-spend, which is notable because rural schooling is horrendously expensive on a per student basis.)

If you rolled back to 60s level spending, even inflation adjusted, we'd be down the bottom of that distribution.
