One of the things I sometimes fiddle with in the back of my head is how to fix school curricula to better serve students and society. One of the stronger ideas I have is that economics (and ideally, game theory) should be taught, replacing a lot of really dumb mathematical holdovers like trigonometric identities for a semester or two.
And over the last few weeks, I've been really wishing that we'd been teaching economics for the past fifty years instead of other silly things, because the blinding stupidity on exhibit in the recent oil debates is really starting to get to me.
