I worked a year for Walmart as a night stocker, and one of the things that I noticed about my third week in was that I was one of the few people working there that wasn't on food stamps. Then I realized that Walmart is essentially letting the government subsidize their ability to offer a wage that isn't even considered livable by federal standards. Absolutely sickened me, but I was locked in the same cycle they were, stuck in an area with few jobs that all paid the same. Thankfully I got out, but working around all of those people trapped in generational cycles of poverty while still working as hard as they could all night and destroying their bodies with bad healthcare was a humbling experience. I wouldn't feel so bad if they were a bunch of asshole rednecks, but I worked with more than a few intelligent people who had fallen on hard times and were doing the best they could with what they had. I was more than a bit of a prick when I started working there, by the end I had become a lot more compassionate. I don't know why I went off on that tangent.

Tl;dr: don't work for Walmart.
