As far as I can see, up until about 1957, the US was doing pretty well in education. Then they rolled out all of these "initiatives" and made the schools into leftwing indoctrination centers. The quality of education started going down at that time.
As it often does, the Left said one thing (We need to improve education) and did another (Let's dumb down America).
Sounds like the Progressive enterprise that Glen Beck elucidates.
