This is two years old, but quite impressive if you haven't already seen it. Hans Rosling of the Karolinska Institute in Sweden reviews the huge changes in the economics of the world since 1962. (Link via a comment by Dave Tufte.)
It's all good, but I especially liked the beginning. He demonstrates that the best Swedish undergraduates know less about a vital aspect of the world than chimpanzees do.
Which, in turn, reminded me of the great, cranky line about today's students from Stand and Deliver: "It's not that they're stupid, it's just they don't know anything."
