[As_You_Wish]

As I said in a comment to another person, if you go down that road, nothing is "backed."

I'm just talking about regular everyday stuff. The US dollar has been exceedingly strong for a long time, due to many factors, none of which is that it is "backed" by gold or baby diapers or star trek transporters machines or orange juice.

This is just a colloquial conversation. If you want to be exacting, I can write 200 pages on it, complete with sources. But are you going to want to read it? or would I be wasting my time writing a long and thorough explanation? Wouldn't a couple of paragraphs suffice and just not have people nitpick in order to score "gotcha" points?
