Well, Wal-Mart is doing exactly what Marx says capitalism will do in that famed passage of the _Manifesto_:
The bourgeoisie, wherever it has got the upper hand, has put an end to
all feudal, patriarchal, idyllic relations. It has pitilessly torn
asunder the motley feudal ties that bound man to his "natural
superiors", and has left no other nexus between man and man than naked
self-interest, than callous "cash payment". ... All that is solid
melts into air ....
Asking Wal-Mart to be nice to its workers seems to be beside the point: it's doing what it must. The situation of the workers can be mitigated by unionization, possibly. That of the petit-bourgeoisie and their small towns which Wal-Mart is crushing seems hopeless, unless some of them are going to be preserved in theme parks or reservations by an indulgent upper class. Certainly, keeping just Wal-Mart out of a given area doesn't much inhibit the general process of disurbanization that it exemplifies, which will continue as long as the price of gas continues imperially down and the cost of racism and classism continue upward. The immediate future would appear to be very large, squarish, surrounded by a large number of private vehicles, and fluorescently illuminated; could be a mall, an industrial park, or "homes" as they call them.
