Jobs keep changing over the years. People used to work on farms and there were no shortage of farmhand jobs. Then later it turns into factory works, then waiting tables and washing dishes in restaurants, and now the latest is gig economy like uber and doordash. I think it is really an entitlement when the world changes and you refuse to accept it and demand someone else give you what you used to have.Working at a restaurant was something of an an entry level job by default when no non-restaurant jobs were available. Now that people can choose what they want to do, it turns out, many of them didn't want to sling hash. It's a structural problem, particularly if you can't make your own sandwiches.
I too want $5 lunch with soup and sandwiches with coffee refill in a sit down restaurant. These days the labor cost (because of cost of living) is so high that legal minimum wage is no longer relevant. Keep raising those limit or paying more doesn't matter as restaurants keep closing and customers keep ordering takeouts in self service places without tips.
Not sure if there's a real way to solve that problem, when some people will always be higher income than the others and economy changes will always be there. Imagine people not eating out when they work from home so they can put a chunk of meat in instant pot or sous vide, and not hiring nannies to pick up kids after school because they can just take a 15 min break to pick them up themselves.
