Boeing used to be a company that put safety and quality first, they revolutionized plane travel with the 737. But recently Boeing has put share price ahead of safety and decided to move their corporate office from Seattle, where the planes are built and engineering is done, to Boston (edit: Chicago, not Boston). Why? Because executives heard that successful companies have corporate offices in a separate location. Then the merger with McDonnell Douglas, who has a horrible track record just made Boeing's quality slide even further. Boeing now parcels out work to subcontractors who subcontract even further and there is no oversight or quality control on the components. This results in "door plugs" missing bolts or having bolts that were not tightened properly on the 737 max.
