google sez:

"Inflation-adjusted public school funding per student in the United States has increased significantly over the long term, with a roughly 34% increase in inflation-adjusted revenue per student over the last two decades alone. Looking at a broader historical view, inflation-adjusted spending per student has risen by over 200% since the 1960s."

This is the bias that keeps us from actually making improvements to the education system. I guess it's easy to repeat and blame money. Kind of like a brilliantly colored red herring.
