> there is a consensus that we need a harmonious, stable and positive society

It's not clear to me that there's any link between China's authoritarian government and its harmony/stability. Taiwan is richer per-capita than China and just as stable, without an authoritarian government.

In fact, I suspect that China will be rich and harmonious as long as it's not at war (with itself or a foreign power). The authoritarianism is just a historical coincidence.
