There's a company in my town, hiring devs for a fully robotic kitchen setup. Ingredients are deposited, machines cook meals. A single person can take care of the joint. You can replace a $100k/month bill on personel for a mid-size fast-food outlet with $10k/month for a few guys helping the machine. No strikes, overwork, just ingredients, meals and a bit of maintenance.

Imagine, you are a 50 joint franchise, that's a whopping 50 mil per year in savings (and few hundred people desperately looking for jobs).

And? Many jobs have disappeared. Many jobs have been simplified with software to require far fewer people, and far less mental effort.
