The USSR and associated countries basically tried to speedrun the industrial revolution and capitalism, to get to socialism and the (utopian) communist society where the state withers away because it is no longer needed. All the untold misery that Western Europe went through over a couple of centuries happened in a couple of decades instead. They tried to force the process and progress. In the end, political pressure from outside and corruption from inside brought it down.
