Norway has roughly the same unemployment rate as the us, but most supermarkets have the option of self service, most fuel pumps are self service (never have someone pumping it for you), and if anyone bags your groceries for you it's kids raising money for their football team or something. Very few people (comparatively) have menial jobs but unemployment isn't really higher. I also don't know anyone who has to work more than 1 full time job to survive. Menial jobs trap people who could otherwise flourish.
