I apologize but you are wrong, if I understood your answer correctly. if I did not understand correctly - correct me, maybe I really misunderstood you....
But... One of the problems with China is that just in the last decade China has seen a rise in incomes and living standards. That has led to some changes. Starting with the fact that population growth has gone down - both the impact of the "one family, one child" program and the actual rise in the standard of living of the Chinese. And as you know, the higher the standard of living, the lower the number of children in families. 1-2 children is normal, but not 5-10 children. And this is a resource for cheap labor.
Oh yes we live in different environments, and just because income of some is higher that does not mean there are no issues. China has huge issues with overeducated people finding jobs in their profession. Still millions have huge debts or credits running for apartments which have been demolished.
Few countries try to counter those cash problems in offering schooling to the working class.
Scandinavia, the Baltic States go that way. China in parts but their economy is still more export driven.
That was not an answer directed towards you actually, it was meant towards all. Wages are too low. Most countries have greedy politicians. Specially Africa has a lot of them. The still US is a rich country. People flogg into the US as they believe that 1500 US$ is a huge wage compared to the 150 they would make in Ecuador or elsewhere. But in the US they lower classes suffer most, under the pressure of a mass inmigration.
That apart the US neither seems to believe in Education.
Back to China, I don't think they can survive without selling their goods into the West.
The EU will be poor just as the US as lower classes will get less $ for more work, which will lead to revolution.
