Its not just an oil problem.
In 2010 the us imported $337bn of oil (according to
Mr Pickens).
At least some of that was used to generate economic activity which offsets this cost. Not all by any means and the efficiency of its use could (should) be improved - thats why we are here after all
At the same time though the US sent $273bn
more to China to pay for stuff than income from stuff sold by the US there.
