Usurious interest can leave people impoverished and destroys families, sure. But we're talking about mortgages, here, and in the general case interest leaves the price of homeownership about the same price as renting, provides additional stability and helps build families. The real thing that leaves families impoverished and destroys them is when they have borrow half a million for a house to live in, only to find out that's only really worth about a quarter million a few years later during the economic crash, thus precluding them from actually selling it and moving somewhere that has an economy where they can work. That's principal, not interest.
