Here are the last two segments from the 20/20 last Friday.  The second one in this post is relatively short and pulls everything together, which is why I'm putting the two together here.  The first clip here mainly goes after Farm Subsidies, and is just fantastic.

John Stossel is fantastic.  Yes, he's a Libertarian (and unapologetic about it), and he does an incredible job of making the common sense Libertarian case for government, whether you see it that way or not.  The fact that ABC was willing to show this at all is a tribute to that network.  Although as I understand it, some of the ABC affiliates refused to show it.

I've previously posted Part I, II, III and IV.
