No.  I'm saying Wal-Mart is moving into a market where it believes it can make money.  It has nothing to do with public service and everything to do with bringing in money.  There are potential consumers, so it assumes demand is present.  There is a labor surplus, so supply is present at lower wages.  I think you're engaging with the issues of what should be, while I'm simply trying to explain what is and why it is.

Be nice to America. Or we'll bring democracy to your country.
