Exactly. The difference between a Boeing employee doing “regulating” versus an ex-Boeing employee who now works for the FAA doing the regulating is significant.

And then few years later we find out that the FAA employee is offered a 3/4 times higher pay in the company again..

Just like wall street executives getting in politics to regulate banking and then go back to highly paid positions or are paid millions in consulting fees for doing few speeches an hear.

Anyway I know that FAA investigators aren't necessarily from the industry (they are engineers in the field and can investigate the matters anyway), but I know little about regulators.
