thanks for the interrsting debate. I am with rdf (I agree that the concept of monopsony is fundamental today) and DeAnander/Izzy on this one.

I'd like to also link Migeru's comments about the lack of resilience to our earlier discussions on hysteresis and irreversible effects (i.e. - after WalMart has "stripmined" a city  and leaves, the old stores do not re-open - there is a net, permanent effect)

In the long run, we're all dead. John Maynard Keynes
