You're arguing against people with personal experience either actually living in China or who study this kind of economics for a living with Wikipedia.
First of all, I am arguing in support of a widely held view, even among all the relevant economists who study this stuff, that Chinese economy is growing rapidly and can be considered a successfull one, compared to similar developing nations, and that the living standards of even the common Chinese did increase quite a bit. So they must be doing something right. Now if someone disagrees with that, then I expect some good arguments to convince me otherwise, and I am afraid "I live there" wont cut it.
Particular Wikipedia which defines "Poverty" as less than $365 dollars a year. I make that in two weeks, and it's still difficult for me to pay for basic necessities here in the US. In real terms, the poverty line in any developed country (even China) is significantly higher than that.
Poverty measured as $1.25 dollar at purchasing power parity per day is a standard measure used all the time. Id be careful to draw any comparisons with the US since they are very different countries and prices are different too. Also, this probably measures real poverty, not the first world "I have a house and a car and a playstation and internet but I am poor" poverty, so yeah it is low by our standards, barely enough to survive.
Anyway, if you want a little more holistic measure, here is Chinese HDI:
http://countryeconomy.com/hdi/chinaMoreover, it also doesn't comment on the substantial changes that has brought with it. Since 1981, China has expanded industrial activity, power generation, and manufacturing on a massive scale but without massive emissions improvement. China has a massive pollution problem that affects overall health, and much of the profit associated with those developments in consolidated in the hands of a small few, primarily in large centers.
By and large, the social and economic conditions in China today are very similar to turn-of-the-century Britain (or slightly earlier). They're a bit of a grand experiment demonstrating how brutal unregulated capitalism truly is. Hopefully they deal with it before they irreparably damage their landscape and water, not to mention citizenry.
Yeah, I am not saying China is without issues. What I am saying is that it is economically quite successfull compared to other developing nations and therefore one should be very careful with any criticism or hasty dismissal of their system (whatever that is). Because it works.
