the results came for the next generation though, and it didn’t need all those 100 years.

I assume you mean the current generation in China? If so, the results seem to be less than ideal, to put it mildly. I would posit that the Nordic countries (and possibly most of the EU) offer better living and working conditions to the working class, even under their neoliberal welfare state. I certainly don't see where China is excelling in that regard.

setbacks are part of history everywhere else too, and don’t paint the entire picture.

The question is; now that China is a wealthy world power, what exactly is stopping them from enacting more radical social changes to make it actually look like a socialist country? How long do they have to wait before power is given freely to the proletariat and the state withers away? From my perspective, there does not appear to be any light at the end of the tunnel.
