How old are these visitors? Are they college educated? I ask because the Chinese grad students I hang out with are for the most part frugal in their accommodations and lifestyle (in some cases out of habit, in other cases because they're sending money back home to family members with medical problems). I'll grant that friends from Beijing or (especially) Shanghai are likely to be the exceptions to this rule.
They are ususally between the mid-20's and early 30's. They buy Levi's because of the cost. A $26 pair of jeans from Sears can be over $100 there. The married guys always come with a wife supplied list. Cosmetics, clothes, and shoes seem to be at the top.
As for education, They all seem to have at least a BS. I would be surprised if a lesser educated worker could leave the China. We had a party for them awhile back. They all had their pictures taken hold shotguns and rifles. They are actually a fun group.
It's the government I have issues with. It's would be different if a free country was attempting to buy us out. A communist country doing the same thing gives me the whillies. They have no problem with making their own people suffer on a massive level to achieve their goals.
