All TLs of Communism (in a real, genuine Marxist sense) taking hold anywhere are non-starters. It just won't work. Communist theory is predicated on the idea that those who control the means of production will pay wages as small as possible, since doing so maximizes profits. This is incorrect, for the simple reason that the same population which provides labor to produce the goods are also the market for those goods. Therefore, capitalists need to pay workers salaries sufficient for them to buy the very goods they are producing. This, in turn, creates a consumer society, in which Communism can never take hold.
