All can be found in the article I posted on a state by state basis for the past 15 years. - plus links to other time frames. On an inflation-adjusted basis teacher salaries have gone down in most states. This has been well documented. I guess all of those dollars in the CATO chart have gone to consultants and administrators because it certainly has not shown up in the classroom either in teacher salaries or per pupil spending.
This might be a good time to remind people again (as I have posted before) -- when comparing demographic group to demographic group the U.S. is number 1 in K-12 education in the world.
Those who post charts claiming the U.S. trails other countries in K-12 education or test scores are not properly taking in account the proper comparison by demographic group which is the correct standard to follow.
