That isn't "real world" Communism, though. Socialist States tended to place a much higher emphasis on welfare than Capitalist states, that's historical fact, regardless of how effective or not they are/were.
Secondly, I never said Feudalism was better. I indicated the key production distinctions between Capitalism and Feudalism, in Feudalism the serf gives the lord a flat portion of that which they create, in Capitalism the proletarian receives flat wages as a petty portion of profits. Feudalism therefore has very different mechanisms, and while horrible, is different from Capitalism.
