Money is created via bank loans. The largest bucket of loans in the US is mortgage debt -- and it's worth trillions more than any other type.
Should this source of newly minted dollars dry up, the US could very quickly fall into a liquidity crisis.
So, yeah, it's easy to shake our fists at high housing costs -- but what most people don't realize is that almost every dollar you've ever touched or earned was born in some other person's mortgage.
