This investigation seems to be turning against Boeing. They will survive, but it almost definitely will cost them far more than whatever they saved by cutting corners. There will also be changes to the certification process, and non-US authorities will take a hard look. Any new incident would become an existential risk for Boeing.
It's important to remember that a company like Boeing isn't a single person. People working on the certification process would usually have incentives that differ from the company as a whole: they do not individually reap the benefits of cutting corners, but bear the brunt of any mistakes, including moral responsibility, possible criminal charges, and an end to their careers.
Such schemes are employed in many industries. Usually, corporate structures and cultures prevent the sort of top-down pressure that people imagine being at play here. Threatening your safety engineers (fire marshals, data protection officers, etc) with job loss for doing their job would result in whistleblowers and lawsuits. It will be interesting to see how exactly this failed at Boeing.
