USSR dissolved in 70 years, but CCP now marks its tight grip for 72 years. Are we heading to the endgame of CCP? Maybe, because of covid. The problem with communism/socialism is always about the economy where the higher up corrupt as fuck enriching their inner circle, and the ordinary people remain poor (yes, 1st world countries also have corruption problem, BUT it's not as severe as China). Add it with no freedom of speech and stuff, including covid as the accelerant, literally will make suffering to the max.
Humans can break with a particular level of suffering, and once they break, the government will collapse.
The CCP has avoided mistakes that were committed by the other socialist nations. It is being said that the main reason for the collapse of the USSR was the crash in the oil prices. But that was just a trigger. The real reason was the huge increase in unproductive population in the central Asian states like Tajikistan and Uzbekistan, which overburdened the European part of the USSR. And China is taking steps to avoid a repetition of that scenario. They have imposed strict birth controls in Xinjiang, to prevent the unproductive population from exploding.
Let me disagree here. There were problems, but others:
1. The real drop in budget revenues due to the fall in oil prices
2. Absolutely unbalanced, manually controlled economy, the efficiency of which tends to zero.
3. Total impoverishment of the population, falling living standards.
4. Internal discord between the "old communists" and almost organized crime represented by the security forces.
Regarding internal migration to the USSR (this is about the migration of Tajiks and Uzbeks to the European part of the USSR). So, in short, migration was an extremely difficult process. To leave the settlement where you were assigned. In the USSR, there was such a concept of "registration" - these are the binding of a citizen to a certain place of residence, you cannot change it yourself, only when you change jobs, get married. In the USSR, there was no concept of free movement. To make it clear - villagers, peasants, in general, until the mid-1970s did not have passports, which means they did not have the right to go anywhere until such an action was approved for them, and it was extremely rare, because everyone tried to "run away" from the village - there people were not even paid for their work with money - most of them were given out with grain, potatoes, etc. agricultural crops and only a minimal part - with real money ... This is the reality of the USSR by 1980 ...
