I have been interested in how Wal-Mart makes money, so I have been looking into the company. I have come to the conclusion that it is nothing more than a scam. Wal-Mart isn't a real independent company considering their payroll cost relies almost exclusively on government contracts. Their workers are subsidized by welfare, as you couldn't pay them that low otherwise. But they are paid so low that welfare picks up the rest of the tab. So, Wal-Mart is exploiting a huge loophole. Not really that big of a deal but it not a real market company.
I don't necessarily object to having government contracts or using government subsidies, hell I do a lot of this as well, just seems like these companies shouldn't be the darlings that they are.
