So I finally just watched 'Walmart - high cost, low prices' and I gotta say it's disturbing, of course the film is going to be a bit biased but do you really think walmart is as evil as they are portrayed? I saw my hometown gutted just like in the film with walmart destroying all local business and becoming the only remaining store left. I am now fortunate enough to live in a fairly affluent area where walmart is pretty small and ineffective due to the large 'buy local' vibe around here. I must say that buying local and keeping your money in your community works wonders.
Here is a link if you're interested, it's definitely worth checking out.

and no I'm not associated with the film and don't care if you buy or not.
