I was on leftie tiktok (as a creator) for a bit and I saw this attitude there as well. I specifically remember one argument around cleaners where someone said that employing a cleaner was, like, ethically bad, and that "after the revolution" we wouldn't have cleaners.
It got me thinking, along with Ann Russell talking about how to treat cleaners (being a cleaner herself), about how we conceptualise domestic service as particularly degrading in all its forms, when, really, why is that? Why is paying someone to do something intrinsically bad?
Like, even in a moneyless, gift economy society, there would still be people whose primary contribution to their communities would be cleaning. Some people like to clean, and are really rather good at it.
I've talked ad nauseam in the past about how British attitudes towards cleaners and other service based positions today are the descendants of Victorian attitudes. That is, both the attitudes of conservatives and many progressives of that time. The trade union movement was particularly exclusionary towards service workers.
I think people on the left thinking about forms of labour can sometimes be worse than people on the right. People who have taken these positions generally just conceptualise them as something you need to do to get by, and there are particular employers where these positions are degrading but in general the jobs themselves aren't.
