This is only a problem in a relatively narrow corridor of the country. Almost everywhere else, Walmart is a staple.

Walmart is a different experience in the places where there isn't social stigma attached to it because normal people don't have any problem going there, but also because there isn't a political apparatus working to deny their attempts to improve their buildings, expand to newer areas, etc.

Moreover, there's a difference between a) shopping there b) working retail there, and c) working there in a professional role.

I'm guessing you get over that quickly if they pay well and provide a good work-life balance.
