Employing a large number of people in small locations all around the country to manually do something seems like the exact opposite of late stage capitalism to me. It's traditional capitalism isn't it?
What I wanted to say, is, teenagers just got better options today than to sweat away in such an establishment
When I was a teenager, I did have a customer service job for a while, but it still was 10 times less stressful than working in a restaurant.
Surely other industries must have similar jobs.
