Another possible solution to the time-tested Imperialist Model is the technology-driven "finance model" (which few have tried; Venice, technically a City-State in the Renaissance, did to great success, inventing shareholding as we know it).
Imagine if the US was, as stated, not getting the best deal exporting scrap (minus the S) to China. This in no way pollutes a model where the US loses on that trade, but borrows from everyone else (but mostly China!) and invests this money at a better rate of return. 30 or so percent of American GDP stems from the financial industry, I am told by Maria. Its the business of deploying capital (creating a world-class finance business in New York and London, yes England), mostly due to fine engineers that linked my Monte-Carlo simulator to the Legal Docs department.
This model only works when people trust you. People will not trust the US forever, but I dont think Bush Son has an arm strong enough to hammer the nail in that coffin. Lets let other people trust locals (say a 98 Asian crisis buildup), and they will come back to industry specialists in NY and the City when it blows.
As long as Asia does not trust itself, this carry trade is one of the most lucrative trades in history (albeit with no central planning, or normally distributed income among US citizens). Remember China and Japan have been paying for Iraq all along! But the guns are the West's, and pretty much America's.
I hope it only goes to hell after I die!
