Did you know that if banks were to practice Fractional Reserve Lending (lending money they do not have) without charging interest it would still be usury, the likes of which is unprecedented in human history?
It's not the interest on Fractional Reserve Lending that makes it usurious, though it definitely compounds the abuse. It is that Fractional Reserve Lending, in and of itself, done on the scale it is done, legally without limit in the U.S., manipulates the money supply. That is, the money supply already in existence.
It manipulates the money supply by devaluing it. In myriad forms, either sooner or later, whether it takes a couple years or decades or even a century, people have to default and foreclose and go bankrupt - not simply because the interest killed them, but because their money itself was devalued, along with every other person's. Think about it. Then the banks reap those assets up: this is the manipulation of money in order to consolidate wealth. And that is usury.
Side note: Any loan or lending (credit) that has any amount of compounding interest, it is usury. I'm not sure of any instances in which just a flat interest price is quoted. Credit card companies are usurers.
