Banks loans may not create wealth. But they promise its creation to the society. The value of the money that they lend out comes from that promise.

And the people who borrowed from the bank create wealth when they repay their loans. The responsibility of the bank is to track it and ensure that it is created. OR that the money lended out is not spent. Either one should happen when the loan is repayed, so the bank does not care which one.

If the banks does not do it (ensure repayment or collect collateral), then all the people who worked for the money loaned by the bank, got their work stolen.

In other words, when you take a loan from a bank, you are actually borrowing from the society.

So watch your banks very closely.
