That’s true until it isn’t. Automation is on its way. Marching ever onward.
The factory I work in built a new building this year that employs 1/4 of the workers as the next newest one and does 2.5x the output.
You still need loaders, drivers, retailers to get anything to the customer. A lot of rich ski and holiday towns can’t staff the stores and Cafe’s, because the employees can’t afford to pay rent in the same towns, so they face a similar issue…
Amazon is already testing robotic loaders, self driving trucks are already in development, and vending machines retail everything in Japan.
Maybe, but there are still a lot of invisible people involved to get the food all the way to your table. And small suppliers cannot afford to switch their whole operation to robots.
