The Ludwig von Mises Institute is founded on free-market ideology of the Austrian variety, and subscribes to militant capitalism, Rothbard, Milton Friedman, etc. Libertarians are basically the only people who read the site.
I'm not implying all Libertarians subscribe to this ideology; Libertarianism is after all a broad category.
I think this article is a good example of what's wrong with militant free-market capitalism though. Essentially these guys put the market above humanity, and I have a big problem with that.
