The Chinese also need a larger working class as they need more people to be self-sufficient. The one-child policy has massively skewed their demographics so they'll soon have more people retired than actually working. The state can't support their millions of retired folk so you're left with factory workers on low wages having to support two parents as well as themselves. That's why you see/hear about crippling poverty in the more rural areas in contrast to the economic booms in Beijing, Shanghai etc. where there are now well over a million millionaires.
