Too big to fail is the term.
And it's a very valid point.
But what will be sacrificed to keep DB floating?
Right. So here's my theory about this, having lived through the GFC etc et al. The answer is: Nothing. Nothing need be sacrificed. The 2000's taught me that the banking and finance sectors are invincible. They're basically like the facehugger stage of the xenomorph species in the Alien franchise. You can't rip them out without killing the host. Governments understand this. If banks fail, where do people get the money to buy things, take personal and business loans? The answer is they don't, and chaos ensues. The banks know the fed HAS to bail them out, otherwise everything collpases.
Zero-balance, fractional finance backed by an infinite money supply issued by a self-regulating bureaucracy is black magic.
The entire system is a giant ponzi-scheme stretching into infinity. Tomorrow will never come, because states have the power to issue their own fiat and are only ever in debt to themselves. There are no fixed lending or borrowing terms for state-issued fiat. It's an infinite loop. The only moderating power to market rates is inflation, and most people don't even really understand how this works.
Here's the thing: The Fed could print enough money to fill the stratosphere, and it wouldn't matter so long as the velocity of money in circulation is controlled. Everybody likes to laugh at the money printer go brrrrrrrrrrrrrrrrrrrrrrrr but the reality is, that shit works. In actuality, it's rarely ever--if ever--the case that over circulation of money is what drives up CPI. 99.5% of the time it's sociological or market-driven. Most of that number can be attributed to good ol' supply and demand. Generational inflation-creep is literally just a consequence of people having generally more money and wanting more shit.
'Ewmegahd! Houses cost 100000% more than they did in muh grandad's day!'
Yeah, ok. That was before union-creep and back then the value of labour was far less, there were less people, cheap rents, more space, and more house and land packages than there was demand, and outsourcing and globalization hadn't cornholed the west yet. Also your grandad didn't want a gaming pc, an x-box, he wasn't paying a net connection and a mobile phone bill and ad finitum,. Honestly, the amount of money in circulation hasn't had as much to do with it as people think.
