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 thing is.... the Chinese culture is so disciplined that they will not rise up to stop this. If things like this happened in Western countries, people will rebel against it and they will vote against the ruling party to remove their power, but this is sadly not happening in China.

Let's not forget that we are dealing with a country with the oldest civilization in the world.... they should be teaching us how to be successful and we should be learning from their mistakes.

I doubt if the CCP or their economy will collapse or end anytime soon.

First, remember the axiom:
Old age is not equal to wisdom! Over the years, dementia comes more often than wisdom!
Second, the east is a delicate matter. And if now the Communist Party of China can restrain the will of the people by force and repressive methods, then as history has shown more than once, the people's patience is not eternal, over the years discontent tends to accumulate, and so on to a critical mass. And then hundreds of millions of people will not be stopped by an army of millions, not by the precepts of Mao ... And yesterday's leaders will be stoned on the squares and roads. Most likely, they (the Communist Party) will not come up with anything better than to distract the people and raise the degree of patriotism with some kind of "small victorious war", For example, for the return of their historical lands ... This may still give 10-20 years of a moderate regime
