I don't know a single true capitalist who believes in rewarding incompetence; although, the federal government seems to revel in it, given the amount of bailouts our tax dollars have been subjected to. We bailed out GM, for example . . . and THAT was a CAPITAL success.
True capitalists believe that incompetence, when not propped up by the government, leads to failure, which leads to a loss of market share, revenue, and eventually means going out of business. Then, those that do business well (i.e., are competent and even exceptional) are rewarded by taking up the failed company's business.
No, capitalism doesn't reward incompetence. Government does. Politicians do, as do people who think that ______ "can't be allowed to fail." After all, epic failures like Social Security and Medicare/Medicaid would never survive as independent businesses (nor would the USPS) if they actually had to compete with other businesses to provide their services to consumers. But, as long as they have the government teat from which to suckle taxpayer dollars from, they'll continue to be incompetent failures of programs and pseudo-businesses.
