I am just pointing out that it is all relative. My friend is a doctor who makes 500k+ and dropping to a lowly 120k would make him miserable. I also have friends who make 25/hr and are fairly content, they don't need drugs to fend off suicide like you implied.
Someone wouldn't spend 30 years working retail in utter misery the entire time, these are intelligent people who have agency. I spent ten years working these jobs and the people who were there for life were relatively content.
