It’s pretty simple how one bank could lead to many other failures, at least in this country. The nanny-state education has set in and some people don’t know how to use the john without government intervention. Had the government allowed such a company to collapse under the weight of its own mismanagement, people would have panicked and done even more damage.
Heck, ya can't even build a john without conforming to a whole rat's nest of federal regulations.
Everything from how much water it can flush, to how wide the door is, to where you stick it...
