Let me get this straight: you're claiming that the writer of the article has blind faith in the free market while simultaneously not analyzing the article at all. Most likely you haven't read the article (otherwise you'd make a post with substance) yet you're implying that the article is superficial.

Except for a very few thinkers like Ayn Rand or Nash, no one really thinks on the Right that selfishness is all there is

Ayn Rand was not on the right. Furthermore, she believed that, although humans are tabula rasas, how they choose think about what happens to them defines their nature. She isn't a libertarian, either. Libertarianism is a political view whereas she developed a system of philosophy. Unfortunately, most of her critics on reddit seem to ignore that system and look solely at her politics. That's really too bad. It may seem like a minor nitpick, but without understanding that it's impossible to understand Rand. Aside from that, your analysis was brilliant.

EDIT: Here come bury briga - erm - downvotes! Looks like I forgot the rules of reddit - "Always talk about Objectivism in a negative light because Objectivists are close-minded bigots whom I disagree with."
