I've had three different H1Bs. Yes, transfers are easy, but they're sure a hell more risky than staying at your current job and enduring whatever you have to.

You're not beholden to your employer, but you have borderline coercive reasons to stay.

Even a 5% chance you and your partner/kids have to uproot their life is a bigger sacrifice than a 30% wage increase, at least to some people.

Great, yes, but you sure as hell don't have "absolute loyalty" to a company.

Its all relative. A burned out American can drop out tomorrow with no short term plan. H1Bs cannot fo that unless they are ready to go back to their previous country.
