I don't shop at Walmart. It isn't hard to avoid given that I live in the city and Walmarts are in the burbs.
The last time that I was in a Walmart with the intent to buy something I got a phone call out of the blue from a friend who asked me what I was doing. When I told him I was in Walmart, he shamed me into leaving the store empy-handed. While most of my friends are what the more conservative of you would call "PC" (from their perspective they are trying to live their values), this particular friend is not. He's a beer-drinking sports fanatic who was in favor of the war (tho not how it was implemented). And
he shamed me out of Walmart empty handed.
It's already documented how Walmart treats its employees poorly.

It's already documented that Walmart's low prices come at the expense of the American worker. Somewhere between 50-60% of the supposedly patrotic corporation's merchandise is from overseas.

It's also already been stated that when Walmart comes into town it forces local stores out of business. What hasn't been stated is that when Walmart comes to town, it intentionally forces local stores out of business by agressively undercutting their prices. That's great news for shoppers,
temporarily.
The thing is, once the competition is gone, Walmart then has a monopoly in the area, and they can raise their prices to whatever they want. A Los Angeles Times article that I read a couple of years ago showed how in the long run the price of groceries actually
increased relative to Walmart-free parts of Southern California when Walmart SuperCenters came into the area.
There's been controversy about the fact that Walmart censors the music that it sells. There's been controversy about the fact that Walmart originally refused to sell the morning after pill in its pharmacies. Now on first glance these may seem like first amendment issues, but think of it in terms of a store that has a monopoly. If Walmart is the only place that women in the area can get their prescriptions filled and Walmart refuses to stock the morning after pill, what does that do to the women in the area?
