US has 4th higher education spending per student in the world, just behind Austria and Norway (US and these two all spend around $15k/student), and behind Luxembourg ($20k). But, national per student spending only really small part of the story. It is more instructive to observe that there are lots and lots of school districts which spend more than $15k, but nevertheless get atrocious educational outcomes, for example New York City, Baltimore, or Chicago. If New York City public schools can spend nearly $30k per student, but nevertheless have worse outcomes than national average, why would anyone believe that more money is what American schools need?
