Depends on where you go to in China, Shanghai and Beijing are still booming but the living expenses are getting steep.
I think Rassah was referring to all the fucked manipulation they do to their money to keep it's value at/near the value of the dollar to make it seem more stable in their attempt to overtake the dollar as a global reserve currency
It,s a lot less sinister than that. They are pumping out Chinese Yuan in exchange for USD in order to keep the value of the Yuan WAY artificially low, and thus the cost of their labor and exports artificially low. At this point it's practically the main reason stuff from China costs so little. That currency manipulation is now hitting a wall repeatedly, and once it can't be maintained any more, the value of the Yuah, and thus chinese labor and manufacturing, will shoot way up. Result will be a lot of fairly well off people, and a LOT of unemployment.
