This is a pretty interesting chart. https://nces.ed.gov/programs/digest/d10/tables/dt10_083.asp https://nces.ed.gov/programs/digest/d10/tables/dt10_083.asp If you go and plug the numbers in from 1970 to something that adjusts for inflation to ~2008, it doesn't seem that teacher salaries have really changed that much, maybe a 10% increase on average? Hardly seems like throwing tons of money at the problem.
