A little example, at the end of 1976 I started managing in a Mcdonald's and had a total hourly crew of 135 on the schedule, when I left in 98 I was doing the same volume of business with a total hourly crew of about 40 on the schedule. All of this was driven by minimum wage increases and reduced profit margins. So if the minimum wage gets pushed up like these idiots want you can be damned sure that the larger operation will rapidly move into further mechanization and all of these uneducated "immigrants" will have even less pay to not raise a family on, so open up your wallets and be a good American taxpayer.
Expensive labor makes expensive machines cheaper. I was in McD land when we made the transition from flat grills to clamshells, and the lunch rush grill crew went from 3 or 4 (and sometimes 5) to 2 or 3 and never more than 3. After I left they added staging cabinets which I’m sure reduced it more (3 probably became a rarity). Now I’ve seen there’s machines available (expensive, until labor costs go up) to make it so the only person that will be needed in the grill is somebody to bring it supplies. It’s a natural evolution. Add kiosks up front and pretty soon the whole store will need 1 person at lunch rush just watching to call the repairman if somebody vandalizes the machines.
