“Boeing already moved its headquarters to Chicago.”
I could never figure that one out. Boeing did this long ago when Seattle was still a pretty decent place to do business and Chicago is Chicago and always in Illinois.
The decision was probably made by the same crew who decided that the 737 Max was Boeing’s plane of the future...
They moved because Seattle and the State tried something very similar to what is happening now. They bumped the taxes on corporations of "a certain size" IE BOEING! Threatened to continue the trend and knew that with the infrastructure already in place, Boeing was "trapped" in Seattle. Well, NOT SO. Why did Amazon start looking for "Headquarters II and III?" Hmmm guesses anyone? YUP! The city and county started eyeing corporate taxes which would apply to, well, first companies with over "X" number of employees (Microsoft and Amazon) and then companies with over "X" amount of gross income (Microsoft and Amazon again). The employee count was so unpopular that they overturned it unanimously only 2 weeks after it passed ... UNANIMOUSLY! We shall see about the additional gross income tax on companies over a certain size as it is only now just now being publicly discussed.
A decent explanation of how Boeing lost it’s way from engineering driven to boardroom finance driven is in this Atlantic article. https://www.theatlantic.com/ideas/archive/2019/11/how-boeing-lost-its-bearings/602188/
