It really depends on the country, and the particular school district. In the US our problem is cash being syphoned off into "not really education." Around 10-12k worth of education dollars are spent per year per student at a public school in the US. This money does not educate the children, or even go mostly the teachers' salaries. The nations that figured out how to get the cash to the people who matter in education are the ones doing it right. Most western countries spend a lot of cash on education; they just spend it in horrifically bad ways.
