"I certainly could be more productive with the leisure time I have and I would say in general most people won't be more productive with more leisure."
agree with this fo sho. It's a pretty crazy hypothetical anyway, things have to keep moving 24/7 in the USA for society to work at all. Road construction often has to happen at night, and emergency response has to operate 24/7. The rewarding aspect is being a part of what needs to get done and helping individual people with their needs. Yeah, a lot of bosses suck and there are lots of work environments which are monotonous, or toxic, or whatever else, but those things are everywhere in life, not just work. Work is inherent in human life as well; before technology and commerce you had to farm or hunt or grow to have food, and work was just constantly a part of everyday life (unless you're like, royalty). American companies like Hershey's use slave labor camps in Africa to this day because somebody has to just grind out the work for things to function (not that I condone that, and it's supposedly going away soon).
My dad grew up on a dairy farm and had to consistently wake up at 4 AM to milk the cows in the barn, in addition to helping out with many other things and just working a shitton in general. He talked about getting a sloppy joe and Coke for lunch every day from school, and sometimes, if he was really lucky, his parents would give him a little extra money for fries. The result of his upbringing is that is he values everything in life and instilled an incredibly strong work ethic in all in his kids. For me, that ethic has always been founded on the principle of "I want to make a difference in the world."
Going off of that, it's important to say that I've often hated work, and I've tried to push the work ethic part of me down lots of times in favor of being lazy, or whatever. The immediate appeal of working less is very high, and I've complained and whined more than my fair share about work. But I know for a fact that I value everything in my life and have never wanted for anything materialistic that I don't have, and I am a better, more complete person in many ways because of the work that I've done. Work has improved me in ways nothing else has.
