A story is told (Who knows if it’s true? It was long before the internet) about how residents of the former Soviet Union bought and sold vegetables. Comrades could buy them from government-run stores at state-mandated prices, but the produce there was scarce and unattractive. The other choice was the black market, which thrived as it always does under Marxist governments. Old Russian ladies kept gardens, a necessity in a land whose soil is not quite adequate to feed its population. They took their lovely produce to undisclosed locations everyone knew about, to sell at high prices. At the end of the day, they returned home with everything they didn’t sell and ate it.

Markets are different under Marxism.
