If you knew anything at all about history you would recognize the point at which major powers begin to die. And the 'what, me worry ?' blind complacency you exhibit.
I'll call your philosophy Mendozaism. There was a Spanish grandee named Mendoza who proudly proclaimed in 1659 that Spain was great because all the world exported to Spain while Spain exported nothing. Trade deficit ? Who cares ? People who think that Spain needs to export finished goods are just being hysterical.
I agree with willie.
