Waaaaay off topic, but "each according to his merit" is a fantasy even if there were no social protections, progressive taxes, or any of the other right-wing boogeymen. Within reason, yeah, and in certain contexts more than others, sure. But in many environments, it is all about who you know, who your parents are, what you look like, what your gender/race is (and I don't mean that white males have the advantage), and how smooth and conniving you are, not what you can do. There are so many people I see around here in positions of authority, being paid vast sums of money with no sense, intelligence, or vision.
Human nature damns any system from being ideal from the get-go. It's all a choice of lesser evils.
