I like the idea presented in The Dispossessed where unpleasant labor is distributed to everyone with relatively short shifts of a few months I think. This is less efficient since, as you said, there is skilled involved in every activity, but who cares about efficiency.
But sure, if people find pleasure and meaning in it, I'm not going to take it away from them. I just don't think that's true for the majority of people in these jobs today. And it's not doing justice to them to praise them for a job they would rather not do.
And the word "unskilled" might not be perfectly accurate but there are jobs that are by design replaceable and "unskilled" is still the best word to describe that until you offer a better one. But I'm also happy to agree to disagree. I totally see and understand your point and we are not too far away from each other
I never disagreed on your second part. These jobs can't simultaneously exist and be a myth but looking at the meme, there are jobs that aren't what I had in mind. So unskilled labor is both created by capital and used to marginalize preexisting occupations like farming if that's what you mean
