this rarely gets mentioned in these articles but it's extremely important. The Chinese food culture is substantially different than the Western food culture, and I don't just mean the items on the menu.

Chinese don't eat raw foods at all, and especially not vegetables, which they correctly (by the standards of Chinatown produce) view as being unsanitary until thoroughly cooked.

They have created a market that is efficient by eschewing the standards of sanitation that Western produce markets use. That's not to say that this is bad. Their food culture is fully adapted to it and it doesn't produce epidemics of food-borne illness in their community because they handle and cook food appropriately. The same approach wouldn't work if it was mostly Westerners buying the food though. A taste for raw baby kale salad makes this entire approach to food marketing non-viable.
