True, but we (society) wouldn't be much worse off than we are now. If Wal-Mart didn't exist, something else would exist to fill the gap, supply and demand must reach an equilibrium.

We should focus on helping people become self sustainable, not perpetually on the dole. Wal-Mart doesn't help here.

If it wasn't for Wal-Mart, there would be a Wal-Mart shaped niche in the economy and whatever filled it would look a lot like Wal-Mart.
