Communism is old, and young. The principals of communal living are the oldest form of human organization. It's also the most common form today if you count small groups like family.

But as an organizing principal for government, it's a baby. The Communist Manifesto was published in 1848. The Bolshevik revolution was in 1917. So the whole idea of communism is < 150-200yo. Compare to capitalism at this age and it's all slavery and settler colonialism; the most massive redistribution of wealth through theft in history.

The logic that communism is a bad system because the Soviet Union should also condemn capitalism because the Dutch East India Company.
