The topic of this weekend's weekly presidential radio address was education. The message? You guessed it: The federal government needs to "invest" more in education -- as do other levels of government -- but instead they are making cuts.

At this point I don't know what more can be said to show how nonexistent is the connection between federal spending and actual education. As we at Cato's Center for Educational Freedom have pointed out on countless occasions, federal and overall spending on public schooling has skyrocketed for decades as test scores have laid motionless; staffing has ballooned at the same time; Head Start has almost no lasting benefits; and federal higher ed spending largely enables massive price inflation and encourages people to enter college but not finish.

The evidence, frankly, is overwhelming that federal education "investment" is really just flushing precious money down the toilet. Which makes me think that maybe President Obama doesn't read our stuff. Or maybe he just doesn't care.
