Currency is akin to an IOU. You pay for your imports with currency which worthless in itself is subject to redemption at some time in the future which is why I referred to it as an inter-generational debt.
That's a run-on sentence, but you seem to be saying that at some time in the future, people might call on the US to provide them with gold in exchange for their paper money. That isn't how money works anymore. Money today (the money of a rich nation anyway) is a commodity like any other and
does have real value in the way that gold or diamonds do and like gold or diamonds, the value is set by supply and demand. And I know your response - but diamonds and gold have industrial value besides their precious commodity value. That's true, but it isn't what drives their prices and money also has a real value: it is an enabling medium for trade (which is the whole reason other countries use the dollar or the euro).
America's economy is critically dependent on the dollar being a strong currency used in international transactions amongst leading countries thus requiring them to hold large dollar reserves and thus never redeeming the debt...
Again, there is no debt there. There is nothing to redeem. You cannot go to a bank and exchange your dollars for gold. A dollar's value is what it is.
...which in effect means America gets other countries goods and services in return for pieces of paper.
Well gee, now you're making a trade deficit sound like a good thing - like we are getting something for nothing. Ironic that you're contradicting yourself like that, but still wrong.
Problems arise when the value of a currency is perceived as not being backed up by economic output and this perception leads to currency devaluation on the world markets. You refer to simple supply and demand and you are right but it is critical to understand the reasons behind falling demand. Large trade deficits are a key driver.
Currency devaluation reduces international confidence leading other countries to look for ways to reduce their dollar reserves thus increasing the fall in demand leading to further falls in the exchange rate of the dollar, leading to further loss of confidence etc...
Again, you are looking at the issue backwards. Economics is competition and so while people like to say the value of the dollar is "falling", it is kind of a meaningless thing to say. Due to inflation, the value of every currency drops. What is meant/implied is that the dollar's value is decreasing faster than previously in history and that just plain isn't true. Inflation for the past decade has been as low as it ever gets.
What
is true is that the value of the dollar relative to
some other currencies is fallling. But that isn't because the dollar's value is decreasing more than normal, it is because those other currencies (specifically, the Euro) are getting more competitive.
As a result, this is good news for Europe, but it does not present the crisis for the US that people like to think it does. As long as our economy keeps growing, we can simply absorb money dumped back into the open market - much like a corporate stock buy-back.
Left unchecked you reach the point where other countries are no longer prepared to accept your currency in return for their output and so to pay for your imports you now have to spend your own foreign currency reserves which were earned by selling actual products with real value.
"Left unchecked" a decending plane will crash. You're talking about consequences that just aren't in the reasonable realm of possibility.
