Again, not all Wal-Marts treat their employees badly. I very much enjoyed the Wal-Mart I worked for, and I certainly don't consider myself brain-dead. Our manager was very kind to us. Yes, we didn't get paid big bucks, but the Wal-Mart I worked for paid well over minimum wage (I was paid $3.00 over minimum wage when I started working there), and very few people were on welfare.
I realize this may be a rarity, but if I had to work for Wal-Mart again, I probably would. I'm a teacher now, but given this economy, and the way teachers are being cut left and right, there's a good possibility I'll end up there again in the future.
