For the last 10 + years Boeing CEO's have made share price and investor short term gains the companies number one priority. In that time they have returned almost 90 billion dollars to investors in dividends and share buybacks. That is money that could have been spent on aircraft development and manufacturing improvements and would have directly improved system safety. This was no accident, it was a choice and is IMO directly responsible for the root cause of the MAX fiasco which is changed a company culture of engineering excellence to a culture of fast and cheap inculcated from the C suite and which has permeated all the way down to the level of aircraft cleaners.
Sadly like example of Exxon Valdez or Deepwater Horizon, Boeing is now another example of what happens when bean counters run a technologically sophisticated and complicated industry sector like it was Walmart.or McDonald's
