What Natasha said
If we were the creatures Ayn Rand's disciples think we are, we would live like bears, who have no civilization to speak of, no language in which to speak of it, and never will.
Which is why the current incarnations of plutocracy, patriarchy and all other 'screw you, I've got mine' politics are, in the deepest sense, antisocial. They're anti-civilization. What betrays the reciprocity of the social compact betrays the most useful trait of our species, the one arguably most responsible for our success. The people who hold these views are free riders, parasites, if you will, on the public good of basic human nature.
The fact that love, friendship, neighborliness and simple courtesy have survived the free riders' defections only proves how strong these impulses are. If government holds that corporations are people but pregnant women aren't, when theft is celebrated and work is punished, when debt trumps humanity, when the economic contracts that really matter are intentionally too complex to understand, let alone follow, these are direct attacks on most of the people, most of the time.
