The situation may be even more dire. Recent work by Susan Houseman concludes that US statistical data systems, which were set in place prior to the development of offshoring, are counting some foreign production as part of US productivity and GDP growth, thus overstating the actual performance of the US economy.
The falling dollar has pushed oil to $100 a barrel, which in turn will drive up other prices. The falling dollar means that the imports and offshored production on which Americans are dependent will rise in price. This is not a formula to produce a rise in US real incomes.
In the 21st century, the US economy has been driven by consumers going deeper in debt. Consumption fueled by increases in indebtedness received its greatest boost from Fed chairman Alan Greenspan's low interest rate policy. Greenspan covered up the adverse effects of offshoring on the US economy by engineering a housing boom. The boom created employment in construction and financial firms and pushed up home prices, thus creating equity for consumers to spend to keep consumer demand growing.
This source of US economic growth is exhausted and imploding. The full consequences of the housing bust remain to be realized. American consumers lack discretionary income and can pay higher taxes only by reducing their consumption. The service industries, which have provided the only source of new jobs in the 21st century, are already experiencing falling demand. A tax increase would cause widespread distress.
As John Maynard Keynes and his followers made clear, a tax increase on a recessionary economy is a recipe for falling tax revenues as well as economic hardship.
Superpower America is a ship of fools in denial of their plight. While offshoring kills American economic prospects, "free market economists" sing its praises. While war imposes enormous costs on a bankrupt country, neoconservatives call for more war, and Republicans and Democrats appropriate war funds which can only be obtained by borrowing abroad.
