Even with automating shitty jobs that no one wants, you're still getting people out of a job and the only way they have of making money. This is kind of how people reacted when Boston Dynamics showcased its warehouse robot. It seems that we need a universal basic income first, but no politicians are willing to do that at least until unpleasant jobs are automated. There's a bit of a chicken and egg problem there. And, on top of this, companies don't care that much about automating shitty jobs because the people in them get low wages, so they don't cost the company much to employ.
