As I understand it, it doesn't matter if they are Chase, or BECU - most banks don't actually own any of the mortgages they issue.
The problem in 2008 was the fraud, the irrational exuberance, and really dumb investments by the investment branches of a few investment banks. The retail arm of, say, Wells Fargo, which issued a whole bunch of shitty mortgages was fine.
Whether or not you think that investment branches of banks deserve to be bailed out is an exercise for the reader.
Not being funny, but Guiliani forced the whole mortgage banking business into insolvency to make a point that some still think was Vendetta. Whatever the case, Guiliani forced a vast capital market to halt, for no reason I've ever learned, and handed a four trillion dollar bill to the taxpayer, for kicks. No wonder Trump likes his advice.
My wife works in banking, for a small local bank. The regulations are heavily skewed against smaller banks. Regulations around consumer mortgages seem to be designed to keep smaller banks out. Unless you have the resources to engage in sizeable software projects, you will have to write your own software, spend a lot of money on software licensing, or engage in a lot of manual work while risking draconian penalties for little mistakes.
So regulatory capture doesn't just mean rigging the game for banks. It's only the large corporations that do the rigging and gain the benefit.
Tech needs to figure out how to combine the power of small community banks. Small community banks can only survive through having superior local intelligence. That superior local intelligence is worth a heck of a lot in aggregate.
