There is nothing wrong with Capitalism. Individuals may be evil, but the system itself is vastly superior to Socialism. At least Capitalism allows you to make choices. You can say to any business, "I want a better product at a lower cost, or else I'll go to your competitor and get it." As a result, Capitalists would say, "THE CUSTOMER IS ALWAYS RIGHT."
Socialism does not allow that. Socialism is a Government-enforced monopoly (ironically, something which Progressives like Teddy Roosevelt had vehemently opposed). If you think you got screwed by a Government agency, tough luck! The bureaucrats will always ignore your phone call, keep referring you to another clerk at another extension in another state, or they'll just put you on hold...forever, if necessary. The bureaucrats know they'll always get paid, so they don't need to care.
