I don't care if this can be related to the current discussion or not, just wanna share it here. But let's hope the case is true.
It's not really relevant because after the KMT era, the three principles of the people and so on, China moved away from dynastic rule towards popular rule. Even if the KMT wasn't and still isn't efficient in practice, it's the principle, the change in popular consciousness that counts.
From then on, elite rule and especially oligarchic rule became a dirty principle which no government in China wanted to be openly associated with.
The longevity of the government will be based in the status of the people, if people are hopeful, able to contribute to political decisions, getting richer etc.
Efficiency level between properly set up versions feudal rule, capitalist rule and socialist rule are vastly different. In the past, there were rich and powerful Imperial Chinese governments, but in terms of productive forces and social development, they have been behind Europe since the late middle ages.
Now, for the first time in many centuries, has China returned ahead again, and it is showing based on a rising life expectancy, industrial power as well as per capita income, which are more important than raw gdp.
