Assuming it was federal minimum wage of $7.25/hr and he was working 60 hour weeks with 20 hours of time and a half pay at $10.875 it would take exactly 9,149,826 years working 3120 hours a year for a total of 28,547,457,120 hours worked. Or if satan is nice and lets him have more time off and jeff only has to work 40 hours a week then he will have to work 15,994,695 years or a total of 33,268,965,600 hours. If only hell were real so billionaires could be adequately punished.

But whatever you want to believe/ whatever makes you comfortable and or happy.
