when I was in college, I worked as much OT as possible, to get as much $$$ as possible that wasn't under my parents' control. Also I did this so I wouldn't have to take the commuter train home in the afternoon with my father.
The avg. US worker probably wants OT to pay debts... It's micro-rationality, while the slogan on the imaginary placard is more macro-rationality.
