Jacob Weisberg, writing in Slate, seems to think that Libertarians are to blame for the current financial mess.  It's actually a rather amusing piece, that seems to ignore the fact that Republicans and Democrats have been in power for... well... for more than a century, and to date, Libertarians have not.  It also ignores the realities of politics today, which has created the exact opposite of the Libertarian Utopia he rails against.  How he thinks that a Federal government as large as we have now can be Libertarian is so absurd that it's insulting.

The existence of a Fed so strong, that its cutting interest rates can balloon the housing market by creating artificially cheap debt, negates his whole argument.  So does the existence of Freddie and Fanny, which are government sponsored entities whose sole purpose was to distort free markets so that people who wouldn't normally have homes would get them at the expense of others.

He tries to explain this basic fallacy by saying this:

Utopians of the right, libertarians are just as convinced that their ideas have yet to be tried, and that they would work beautifully if we could only just have a do-over of human history. Like all true ideologues, they find a way to interpret mounting evidence of error as proof that they were right all along.

Right.  This is the same kind of thinking that scores abstinence as having a less than 100% effective rate at preventing pregnancy.  Because as long as you say you were trying to abstain from sex, and have sex anyway, you are still considered to be abstaining.  Likewise, if you say something is Libertarian, even though it doesn't meet any of the criteria of being an actual Libertarian solution, it's still somehow a failure for Libertarianism.
