Usually people study a subject because they're at least interested in it. What you're saying is like asking a surgeon to work in IT, for instance, just because they're paying more. That's not a fair game, we're humans with our skills, perks, defects... you can't pretend everyone moves like a pawn just for money.

Boeing, like many other companies is playing the game of "maximise the short term profit" and as usual the easiest way is to cut labour costs. That's why they're in this position (poorly built planes, killed HUNDREDS of people etc.)
