Walmart, bah humbug!

Why is Walmart always under attack? No one has a gun to anyone's head. No one is forced to shop or work there. There's plenty of other options when it comes to where we buy things. Walmart has low prices, they stock everything under the sun and millions of Americans have chosen to work and/or shop there. They must be doing something right? Oh wait, they make money, a lot of money. And that's bad! Only in America...
