America the Ironic

So Libertarians in America are apparently anti-authoritarian and pro-free market. But why be against publicly elected authority figures rather than those who reached such a position through cutthroat individuality. At least in America the government is chosen by majority vote (including the electoral college), but the capitalist elite represent nobody but themselves. The fact that they have so much political sway through their lobbying and campaign donating is the subject of much ire from the citizenry.

True libertarians are wary of autocracy from the private sector and include Anarchists, Social Democrats, and a few of the more self-aware right wingers. There is also such a belief as libertarian communism, but since it has never been properly implemented it has less credence than other theories.

TL;DR: If you think you're anti-authoritarian then you'd also better be against individualistic capitalists' power.
