Which is essentially "we want to be equal when it comes to the good things and unequal when it comes to the bad things". I'm sure there are plenty of people who want to be equal to professionals who work 70 hour weeks when pay day comes around, but they don't want to be equal when it's time to work.
Are you saying that the likelihood of slacking off is higher for certain groups than others? I doubt what you say is 100% proven or even probable but that said the likelihood of this happening is equal across all groups
No, and I have no idea how you can misread my comment to mean that. What I'm saying is that most people don't want to work 70 hours a week. But most people would very much like the pay that you get from working 70 hours a week. If you allow them to choose both sides individually, I'm pretty sure they'd choose the low input and high output.
