Gumby,
Why can't we pull our military out of all those countries, let them start accepting Euros or other non-USD currency, and then the US will owe foreign demoninated debt.
Then when we run out of money, we just start printing foreign denominated currency, the same we do with USD to pay our debts off that.
Problem solved!
In all seriousness, in my first post, this is what I was talking about. The USD needs to be the world reserve currency in order to maintain our global ponzi scheme. If OPEC started taking Euros for oil, then the USD would plummet. It's pure supply and demand. Because all countries need oil, all countries need USD, and thus the act of them trading their currency for USD drives demand of USD up and keeps the global value high.
The problem with simply "letting" them go off USD, and saying "screw it, we will keep our USD in house and start domestic in-sourcing of manufacturing" is that the stuff we need is based on a global marketplace.
Even if we pumped our own oil here in the US, if the value of that oil globally is high relative to the USD, then it drives the USD price of it up, because the US companies could just as easily sell it overseas. This would cause gas prices to go up 2x over night and 10x over a few years.
Even if we grew our own food (which we do), it's priced on a global marketplace. Americans will be priced out of buying US-grown corn because the price isn't simply based on USD, but it's based on USD relative to global currencies since other countries buy our corn.
Essentially, over the years as the military-industrial complex has grown and is tied to our current fiscal policy, it's made us dependent as a nation on the need for continued currency hegemony. I'm afraid our best course of action is to continue as is and let the system destroy itself in 20 to 30 years, rather than try to dismantle it all at once and have us all plunge into an immediate depression that we never get out of. At least we get another 30 good years out of it!
