on one hand people complain about sweatshops but on the other hand when the repetitive, soul crushing, low paid job is replaced by technology people complain as well. you can't have it both ways.
People would rather have a low pay repetitive job and be able to barely afford living rather than no job at all and being homeless
Also the "people" of the beginning of your sentence aren't the same people as the "people" in the end of your sentence. People complain about min wage repetitive jobs but it still beats being homeless
