>the general public is under the impression that you deposit money and it stays there

After decades of reruns and annual 24-hour marathons of "It's a Wonderful Life" I don't think the general public is unaware of this very basic aspect of the banking industry. I knew by the time I was 8 that the money was in Joe's house etc., and I didn't grow up in a household that had any particular knowledge of the banking & finance industry.

If you asked most people "Do banks keep all of the money everyone deposits in one big vault, or a bunch of little vaults, all of the time?" I think most people would at least have some vague notion that the answer is "Um, No?"
