i wrote in another thread about how the coverage of the problems with Communism is heavily distorted. Sure, there were problems but they tend to be wildly different to the ones that the free-market obsessed corporate media want to tell you about.
e.g. the "long queues" in Russia in the 1970s and TV footage of shops with nothing but "plastic buckets" etc left, is meant to tell us that central planning doesn't work, as they under-produced needed things and over-produced buckets. So it gets turned into a simplistic "capitalism is the answer!" mantra when the real event was actually about different government responses to externally-caused inflation, and how they can backfire. What actually happened in Russia is this:
OPEC raised the price of oil (AKA the 1973 oil crisis), this causes the Russian currency to devalue, as at the time they were a big oil importer. this caused strong inflation. The government was worried the inflation would erode popular support, so they implemented price controls. But the currency was still devaluing, so store-bought goods became ridiculously cheap. People started hoarding goods, which causes shortages in the shops. This then lead to a black market, and people hoarded even more. Eventually, everything with black market resale value was out of stock. The "plastic buckets" etc were the only things left in shops not because they "over-produced" buckets, but because people don't hoard stuff like buckets, not matter how cheap they are.
Obviously I'm only skimming the surface of the events, but what really happened was a much more interesting and complex chain of events that teaches you something about real economic impacts of decisions, and human behavior, compared to the knee-jerk "capitalism rocks!" version. Price controls aren't a specifically "communist" thing.
