2. Double income isn't necessarily that much income, if you're making 35k giving up sleeping to get 70k seems like a pretty poor trade.
Also, no, never. I would never work twice as many hours (assuming we're taking a base number of hours between 6 and 8) for twice the pay. You effectively earn less money (due to graduated taxes) and you have to give up all the creature comforts of life. Going from working 8 hours a day to 16 hours a day would drastically lower the enjoyment I got from life and probably end up killing me from stress.
I personally really enjoy working, and never felt that working 80+ hours was a burden. To be honest I actually look forward to getting up and getting to it most days.
With all that said, the growth I had just wouldn't have been possible on 40 hours a week of work. So I credit the long hours with the creation of a lot of the luck and opportunity I experienced in my life.
A personal bugbear of mine: your point is directionally correct but expressed incorrectly. Under marginal tax rates you do not earn less money. You take home less per hour past a certain point, but are still earning more overall.
I'd be a lot less bothered about people getting this wrong if it hadn't been turned into a political football in recent memory.
Because he sacrifices his health in order to make money.
Then he sacrifices money to recuperate his health.

the result being that he does not live in the present or the future;
he lives as if he is never going to die, and then dies having never really lived."
