He was a white collar working class guy. His work history is full of positions at various tech companies working as an engineer. It doesn’t appear that he was handed any sort of dynasty.
He was upper class, and he had better opportunities than your average American, but he was still a worker.
Also worked there. There is no McDonald’s that has ever allowed tips. It’s against their corporate rules. I even saw an employee get written up for accepting a tip, once.
