I’m not sure how much of this information to actually believe, but The Consumerist says:
Only 1.2% Of American Spending Actually Ends Up In China
"Well, as this report from the Federal Reserve Bank of San Francisco reveals, for starters, 67% of American spending is on services — and 96% of the services we buy are totally made in the USA. So that takes out a big chunk of spending right there. On top of that, only 10% of American spending is on durable goods. And USA still dominates that category, clocking in at 66%, while China is only 12%.
It gets even better.
11.5% of what US shoppers spend goes towards goods and services produced overseas, but 36% of that goes towards US companies and workers in the form of paying for transportation, wholesale, and retail activities.  In the final analysis, only 2.7% of American spending is on ‘Made in China’ goods, and only 1.2% of the American expenditure is on the true cost of the goods. So for every dollar spent on a plastic ‘Made in China’ ‘Robert-Cop’ doll, 55 cents ends up in the pockets of American companies.”
