I think that is still along way off.
It will be too far gone until average American realizes what has happened. Even after September 11th, the average American really believes nothing too bad could happen to them. We are a pretty naive country.
I say Americans will batten down the hatches (is that how you spell that expression, anyway..) and take the Subway job, the Wal Mart job, the paper route. Two, three four of them and try to weather it. For a long time, they will think it is only temporary.
Couple that with the fact that we now have a huge population that comes from 3rd world squalor and won't even consider revolting against what is a massive improvement in living standard.
