They would point out houses and say, yes, 40 people from China all live in THAT 2 bedroom 3 bathroom house. 

I know first hand that no one carries cash in China. 

Made in China.

Most importantly, China and India (and Asia in general) are in the process of taking over as the world's main economic powers and the reality is we can't compete against their cheap labour. 

China is the resource power-house. 

For example, if China invades Taiwan and Taiwan implodes its chip foundries that would be really really bad for the world...

Plus international buyers specifically from Mexico, Canada, China, Brazil, India tend to invest in Texas or Florida.

We had our ash tree population decimated by the emerald ash borer beetle, which is an invasive species from China, but they are pretty hardy and survive -20F pretty well

I am looking into getting manufactured homes built in China.

I do not, but you are correct, there are a bunch out there - mostly China based.
