If these three died, it might be a loss to the country. None of them is as important to the country as Xi is to China. The resilience of the CCP, in light of its dependence on Xi, can only be upheld through the absolute suppression of freedom. But the average daily life is certainly much more enjoyable than in NK.
If Xi Jinping died suddenly, it’d cause serious instability. His centralization of power erased clear succession plans, so top CCP factions would likely fight for control. Markets would also freak out. Long-term? Either a return to pre-Xi more collective leadership or another strongman doubling down on Xi’s approach. Centralized systems with no backup plans are fragile.
It’s possible that with technology like absolute communication control and ubiquitous surveillance the chance of internal unrest or revolution is greatly reduced. And as long as the country is growing and the average citizen is getting richer they’re much less likely to get unruly. It’s like startups: growth solves all problems.
Much more stable than the government that has Trump, Musk and Vivek calling the shots, that's for sure.
