We already spend more than any other country per pupil. Many of the "broken" school systems have received massive influxes of cash (billions) and seen no improvement what so ever. Schools can only go so far it seems.
2 Billion spent in Kansas City to fix the schools. No appreciable result. I'm not convinced in the panacea of education. Something else is at work. The by country PISA scores are quite interesting.
