Matt Stone and Trey Parker are Keynesians - I will hear no dissent on this one.
Maybe they're libertarians or maybe they're not. They've been reluctant to be very declarative on this. All that seems clear to me from what they've said is that they don't like the right or the left. That's fair enough, and a lot of people think that means they're libertarian. I'm a little skeptical of that as a guy that's frustrated with the right and the left and not a libertarian. But fair enough. If they are libertarians, they are Keynesian libertarians.
The mockery of classical thinking is throughout (including of the idea that interest rates were kept too low in the boom), but the good stuff starts at 13:20.
Stan gives us a critique of the politicians
Kyle gives us Keynes
Jets apparently like to snort a bit too
