This has always been my opinion, you can only go so far with a strong man driven - authoritarian regime, eventually it will implode. China was very poor not too long ago, people subsisting on next to nothing. People are not questioning anything, because they are only now entering the middle -class workforce. When these folks move to the next level in the rung, they will start questioning and demanding what we in the west consider fundamentals of democracy - free speech, diversity. You can install a cyber wall, block off all western press, but your people are traveling to the west, in fact, Chinese tourists are the biggest contingent to Europe. You cannot prevent the dissemination of ideas, and ideas are more powerful than a nuclear bomb!
