If you think you’re stepping on the janitor, maybe you should stop.
It’s a job, not a caste. When you apply to work somewhere as a janitor you expect to work as a janitor. Don’t pity people doing a job that pays less, you have no idea what their story is or why they’re doing what they’re doing.
And if you think you aren’t adding to collective wealth and making salaries go further and further than they have before by growing the pie, maybe you should switch jobs and find one that keeps that pie growing.
