Power is doing something and then saying "what are you going to do about it?"
The supreme court takes bribes and says "what are you going to do about it?" They clearly have the power to take bribes. Nobody appears to be able to do anything about it.
Congresspeople trade stocks of companies they regulate in a gross conflict of interest, then defend their ability to be corrupt as a right. "What are you going to do about it?" Congress clearly has the power to be openly corrupt without consequences.
The 2008 crisis was wall street telling the government that they have many answers to that question. "Too big to fail" was born to capture the idea that there is an entity so powerful there are no reasonable answers to them asking "what are you going to do about it?"
Boeing is too big to fail. Boeing knows that there is no one with the will or fortitude to do anything about putting profit over safety. Investigations to make it look like you're doing something, sure. Canning a few low level employees that you can pin blame on, no problem. Sacrifice a contractor? That's what they're there for. But to hold a CEO or shareholders responsible for gross mismanagement in any kind of meaningful way, threatening all other American oligarchs and hordes of people rich enough to say "what are you going to do about it?" without answer?
Admiral Rickover, the father of the nuclear navy, is the past's best answer to Boeing. He deeply understood the forces at play. He had this to say to congress:
Political and economic power is increasingly being concentrated among a few
large corporations and their officers - power they can apply against society,
government and individuals. Through their control of vast resources, these
large corporations have become, in effect, another branch of government. They
often exercise the power of government, but without the checks and balances
inherent in our democratic system.
