It's one thing to support a certain version of capitalism as one's ideal form of government/economy. The state capitalism that actually exists to some extent in the real world today is a very different thing. I'd be shocked if even Rand herself would defend it.
For one thing, among big business, it is more of a de facto socialism than capitalism. For instance, consider all the multi-billion dollar bailouts Consider the fact that -- at least in the USA -- CEOs pay less in taxes as a percentage of their income than their secretaries or the average worker. Consider the billions of dollars big business uses in campaign contributions, lobbyists and various legal and illegal forms of bribes to control the government and get more effective rights than the average person. Consider why at least in the west most CEOs, executives and wealthy people are disproportionately white and male. Why does the median black man in the United States make 2/3rds the amount of the median white man? My point is that even if the rules of a game of Monopoly are fair, it's a different story when someone cheats at the beginning of the game and starts off with all the properties. Maybe people would be more tolerant of big business and rich CEOs if they thought we had all started off with the same amount and these people got rich via a meritocracy of some sort, but that is clearly not the case only one of the many proofs is the income gap with race. Indeed, I think that sums it up quite nicely: many everyday people are emotionally hostile towards big business and wealthy executives because the United States and the global economy is so clearly not meritocratic.
