Is your economy better ? Yes
Is the cost of fuel cheaper? No but you can't blame the Chinese solely for that
Is employment up? No it is the lowest it has been for a long time.
Do they treat there workers fairly? Probably not but alot of workers did not go back to the factories after chineses new year deciding they can make a better living on the farm after the government realized they need to feed 1.3 billion people and gave them better incentive to stay.
Do they follow the same pollution and environmental codes?No Has Australia and America signed the code NO. China is getting alot better with the environment still has along way to go.
Do they produce safe non toxic food and medical products?Yeah they have problems but why do the big western countries just blindly bring them in and sell.
Alot of Western countries closed down there factories in China this year because the cost of living in China is rising (wages, food and real estate etc) and moved there manufacturing to other third world countries.
That will give you other countries to pick on.
