That doesn’t mean people who work jobs in the former category deserve ridicule or disrespect. But the distinction is important because finding workers to fill an unskilled role is just a matter of finding said able-bodied person, while for the latter you need some kind of system of education, training and/or apprenticeship (either explicitly or effectively) to be set up and functioning to even have an industry that depends on those jobs.
Not everything is some silly game of political fighting through language. Some things we actually need terms distinguishing “this” from “that” so we can have real world conversations about them.
