Boeing doesn’t need to fail. They’re not going to, government assistance or not, they are still a profitable company of their own right. This isn’t a case of bad investments like in 2008. So unless every company buying aircraft cancels their orders, which they won’t, Boeing will continue to be fine. Besides, simple fact is Airbus doesn’t have enough production capacity to replace Boeing.
That said, I would love to see their stock price tank. That doesn’t bankrupt the company. It will fuck up their investors though. And those investors are the ones who would demand new management and, if they act collectively, can actually force new management to happen within a year. Any shareholder can put forward a shareholder resolution. A shareholder resolution could replace any or all of the company management. And if a majority of shareholders vote for it by proxy at the next annual meeting, then that’s what happens.
If I were a Boeing shareholder, I would put a shareholder resolution that upper management must step down within the next 8 months, and the company headquarters must move from Washington DC back to Seattle where they build airplanes. Furthermore, the company charter would be amended to say that only someone with an engineering background may serve as CEO or in certain other upper management roles.
