Libertarianism is one of the more popular utopian schemes to emerge in the last twenty years. My rather simple understanding of it boils down to one phrase: the free market cures all ills. Suggestions to the contrary tend to garner immediate and vehement (Hi, Denis!) reaction.
I have lots of reasons to have more faith in the government than I do in corporations. One is that government is meant to represent us all, while corporations don't have to answer to anyone but their stockholders. Another is that government -- at least those that pretend to follow democratic ideals -- can be changed with every election until the people find themselves with representation that satisfies them. With businesses, your only hope is either to find another corporation that doesn't follow the same business practices or go without.
I ran across a very useful site that pulls no punches in critiquing the libertarian mindset, and offers some very interesting responses to Libertarian evangelism. I'm posting it here so I can refer back to it again when the need arises.
As I'm sure it will.
