If no one did shit jobs who would clean up shit? I use to be a janitor at a nursing home, cleaned up a lot of blood, vomit, shit and piss and those were the easier messes, trying cleaning a bed of some dude who just died and refused to move from his bed for 3 months before hand, of course the job sucked dick and nobody wanted to do it but that doesn't change the fact that someone has to, things like cleaning and service industry jobs suck but they are a necessity.
