It doesn't actually work the way it's portrayed in It's a Wonderful Life. The banks don't use depositor money to make loans. I suspect you will think what they actually do is even worse. Look into fractional reserve banking.
replyNever seen that movie but did watch a documentary ages ago about fractional reserve banking yes.
replyThe bank still uses the deposit money in that system. You are right to point out those same people on the street I mentioned would freak out even more if they knew that banks essentially lend out more than we deposited and also that they might sell your debt and all that jazz (I bet most people either never understood what happened in 2008 or forgot already other than a vague "yeah mortgage crisis")
