A dollar saved is then a dollar used to prevent a bank collapse.

Why would we want a bank to not collapse? Most should. They have moral hazard, they should collapse if their lending was a shoddy as has been reported.

You don't get nuthin' for free.

Me? No, but banks do. They legally create money without contributing to the overall health of the economy. Demonstrating how they can do this would require another post. Noting the interest on unloaned money was as far as I was willing to go down this rabbit hole, but I can assure you it is a deep and troubling one.

BTW, Say's Law is crap. Its proponents have a blind spot for the role played by bank-created money. That, too, should be part of a future post.
