Penn Jilette's Great Rant

Most of those who read the online libertarian rags have seen this, but its awesome enough to require repitition

What makes me libertarian is what makes me an atheist — I don’t know. If I don’t know, I don’t believe. I don’t know exactly how we got here, and I don’t think anyone else does, either. We have some of the pieces of the puzzle and we’ll get more, but I’m not going to use faith to fill in the gaps. I’m not going to believe things that TV hosts state without proof. I’ll wait for real evidence and then I’ll believe.
And I don’t think anyone really knows how to help everyone. I don’t even know what’s best for me. Take my uncertainty about what’s best for me and multiply that by every combination of the over 300 million people in the United States and I have no idea what the government should do.
President Obama sure looks and acts way smarter than me, but no one is 2 to the 300 millionth power times smarter than me. No one is even 2 to the 300 millionth times smarter than a squirrel. I sure don’t know what to do about an AA+ rating and if we should live beyond our means and about compromise and sacrifice. I have no idea. I’m scared to death of being in debt. I was a street juggler and carny trash — I couldn’t get my debt limit raised, I couldn’t even get a debt limit — my only choice was to live within my means. That’s all I understand from my experience, and that’s not much.
It’s amazing to me how many people think that voting to have the government give poor people money is compassion. Helping poor and suffering people is compassion. Voting for our government to use guns to give money to help poor and suffering people is immoral self-righteous bullying laziness.
People need to be fed, medicated, educated, clothed, and sheltered, and if we’re compassionate we’ll help them, but you get no moral credit for forcing other people to do what you think is right. There is great joy in helping people, but no joy in doing it at gunpoint.

Who is at the other end of the spectrum?  Well, how about Brad Delong arguing for a return to technocratic rule by our betters

America’s best hope for sane technocratic governance required the elimination of the Republican Party from our political system as rapidly as possible.

Technocratic utopia is of course a mirage, a supreme act of hubris, that any group of people could have the incentives or information required to manage the world top-down for us.  If I told an environmentalists that I wanted ten of the smartest biologists in the world to manage the Amazon top-down and start changing the ratios of species and courses of rivers and such in order to better optimize the rain forest, they would say I was mad.   Any such attempt would lead to disaster (just see what smart management has done for our US forests).  But the same folks will blithely advocate for top-down control of human economic activity.  The same folks who reject top-down creationism in favor of the emergent order of evolution reject the emergent order of markets and human uncoerced interaction in favor of top-down command and control.
