You misread the chart: it plots GDP/capita vs $$ spent per student. You have to normalize it with your eyeball. And it doesn't matter; you can normalize it any way you want: the US spends more than almost any other industrialized country per student, whether raw or by % GDP. If you think the US is a nation of dumbasses because of infotainment expenses and advertising, perhaps you have some evidence for this?
