It goes other way round too. It might just be that the your higher salary is not rational, you got lucky or got unfair advantage.
Like, in the bottom of your comment, you made up situation that might just not apply. Or might just not counteract anything

People go out of their way to rationalize and defend unfair or damaging systems.
