So we need a tight well trained unit of 320 million people. Of course they would be suspicious of, and feel superior to, immigrants and foreign H-2B workers.
I suspect anyone becoming indispensable to a community might earn respect as long as they weren't making a profit from it, and a big profit would have the opposite effect. A pot dealer for example, indispensable but resented if he/she starts living flashy.
On the other hand, service workers like janitors, waitstaff, maids, even bartenders are indispensable to the community, but don't get much respect no matter what color.
