Taking minimum federal wage of $7.25 Bob Cratchit would have around 73 hour work weeks. That makes around 10-11 hours a day every day or around 12 hours Monday to Saturday. It skews numbers, but still the destitution allegory works.
I'm not an USA-ian.
I suspect Scrooge kept Bob Cratchit working for more hours than what's in the modern workweek, skewing the per hour.
Not that that's an argument against raising the minimum wage today.
