If Xi ever loses power, he may end up in front of a firing squad, or simply disappeared and buried without a trace. That's the thing about a term-limited non-hereditary dictatorship where the dictator holds absolute power - the structure is inherently unstable - the temptation is always for the dictator to entrench himself in power as Xi is doing now. If the Politburo doesn't quash Xi, he will become President-for-Life, because stepping down will mean going into exile to avoid the wrath of his enemies.
The future of China is at stake in these palace intrigues.
An economic crisis will ramp up the heat.
The Deng Era is over.
