Except that Walmart has lobbyists looking to funnel more customers their way (they are not along). They also have identified people getting off food stamps as a large risk for their business model. Walmart found out that there was room at the trough, and stepped right up.
Again, many companies do this. Heck, most large companies use the Gov to either get customers or limit competition. But a lot of people doing it doesn't make it right.
Walmart has lobbyists getting people on food stamps or making sure they use the food stamps at Walmart? Do you have a source for that?
