You know how there's money? Well, funny story: it happens that most of what you use in your day-to-day life isn't actually money created by the government, but credits, created by private institutions.
And Free Thinkr adds himself (again) to the ranks of the economically clueless who makes people around him more ignorant.
Please ignore him, Beth.
It's much simpler than that. Money you can't get to is useless, no matter how real it is.
The money that you deposited at your bank isn't at your bank. They either lent it out to someone (who has it now) or they invested it with someone (who has it now), in either case because they need to make money on your deposit both to pay you interest and to keep the lights on in their building.
But if they can't get the money from the people who owe it to them, they can't provide it to you.
I have a bank account in Oxford, England. I could have a billion pounds in it and still not be able to make rent this month, because it takes something like a month to send a letter across the pond and get the bankers to wire money to me.
The bank has an account with Lehman Brothers/AIG. Which means that my billion pounds is "really" in New York, buried under five hundred tons of falling sky. So if/when the bank gets its money, it will give me mine. And in the meantime, no sensible person would accept my debit card.
