This begs the question:
If "the people who owned the banks" purchased "land and homes", how did they pay for it? With folding money, with money held in some sort of bank account, credit?? from their mates? What was it? If we can find out the answer to that question maybe we can work out a way of protecting cash and assets, should everything go belly up in this current mess.
The purchase was a book transaction only they took the property for repayment of the debt. The old land title deeds used to record this.
