Well, Walmart had gotten a firm grasp on the "great" reletivly new idea of monopolization.
You see, they buy out all the "mom and pop" stores. They completely overtake all other supermarkets. They locate themselves everywhere and force people to go there. It's a brilliant ideology of marketing but, unfortunetly, one that allows few others to take a piece of the pie. By removing the competition and locating yourself everywhere, you have created an iffalable system for creating a monopoly. Capitialism at work, baby. There is no way to stop it. Unless you vote Democrat that is.

P.S. By the way, I'm not a business type. This is just how I believe it works.
