Wow. You must have done a lot of reasearch to get such a logical essay. Wal Mart used to piss me off anyway, but now it pisses me off more. Knowing our crappy gov't (hackBUSHcough) they won't do a damn thing, though. Why don't people just stop shopping at walmart? I hope this gets out to a lot of readers. The anecdote in the beginning is certainly a catcher, but the end is a bit confusing and wordy. I know what you mean, but maybe you could edit it a bit for added impact? Cool.
