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.
