I firmly believe that socialism kills itself if left to its own path. But, in the process a massive number of people also die. That's the rub.

Free markets are very resilient. Capitalism is the host that the leach of socialism feeds off of. Socialist never seem to talk about where all the wealth comes from. They use straw men and point to colonialism but that's about as weak of an argument as saying the problem with the USSR was Stalin being a monster.
