Basically it means that if rich people use economic power to take advantage of the rest the state shouldn't prevent them. It looks like lazy-fair, which is basically how the a few capitalists take it, they think themselves being lazy and rich is fair. Those aren't the worst capitalists. The worst capitalists work very hard finding new ways of exploiting people. It is only one of the many things Libertarians and Conservatives in America agree upon in because it gives primacy to unregulated markets to create economic injustice and harm humanity.
