I think in some cases it is far more than a marginal increase. I make just $120k at one of my jobs but I could make $400k+ at a job for a company far less ethical. Hell, a guy I know hit $700k one year at Ye Olde Meta (that did include exercising options though).

The allure of being able to retire early is nice. But instead of seeking high paying jobs I just mix and match multiple low paying ones from smaller companies and achieve roughly the same thing with less stress.
