alt Hacker NewsTechnically true I suppose. But go ask the average person on the street where the bank gets the money they lend people for mortgages and cars and such and I guarantee you the number of people that make that connection is going to be much much smaller than you seem to want to suggest.
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.
