If you watch the film The Founder, it shows how Ray Kroc expanded the McDonald's franchise into a global empire by buying the land the restaurant sits on. That's how they make most of their money.
Okay, so what? We'll, they will never have to raise wages or offer benefits because even if the McDonald's closes because of the “labor shortage” they will still own the land beneath it. The value just grows and grows while contributing nothing to workers or society.
