From Bryan Caplan:
Today my 8th-grade homeschoolers take the Advanced Placement test in Macroeconomics. Back in 1989, when I took this exam, it covered little more than 1960s Keynesianism. The current test is marginally better. Now we've got long-run Aggregate Supply curves and long-run Phillips curves to remind students that pumping up demand has clear long-run dangers and little long-run benefit. But this AP is still far worse than it should be.
The biggest lacuna: There's essentially nothing on the fundamental question of macroeconomics: Why are some countries rich and others poor? Short-run macro stabilization policy questions outnumber long-run growth questions by at least 20:1. Part of the reason is probably the legacy of Keynesianism: "In the long run, we're all dead." But the main reason is that the test writers fear to be empirical - even when the empirics are clear. Saying, "Economic freedom is a major cause of development" just sounds too ideological, even when the statistics are pretty clear and the natural experiments are crystal clear.
For the first time in a very long time, I will be teaching Principles of Macro at my university. Hopefully it will pass the Caplan Test.
