Earlier quoted context omitted.
The daycare owner didn't want $10, he wanted to go home at 4pm. You're missing the forest for the trees.
> The daycare owner didn't want $10, he wanted to go home at 4pm. Then he should have set the late fee to as much as the amount he wanted to go home earlier. Which would still be the same amount for every parent regardless of how much money they had, because which parent is late has nothing to do with how much he values not being able to go home on time.
How about instead of a fine you give the kids to CPS. You go home on time, the late parents never come back, or if they do they're never late again, and you win.
I guess the point is that monetary punishments don't seem to work when companies can consider it as 'cost of doing business.' If we start taking away the company's hypothetical metaphorical children when they're late to pick them up then they have a reason to listen.
