I think Boeing has a very deep hole to climb out of, and they will be losing some business for a long time because of it. They are also apparently still digging the hole deeper...
But ultimately they are too big to fail, and max failure would equal Boeing failure in all likely-hood. That's their bread-and-butter income stream. The can eat it for a year+ because they have access to lots of cash but not forever.
And it's not just their US economic impact which makes them too big to fail... numerous airlines are depending on max availability and few of them can wait 6-7 years for an A320 slot.
