You're confounding affluence with the difference between physical/mental labour. I've done both hard physical labour and hard mental labour, and what OP says is totally spot on. Hard physical work, even when excruciatingly tough, is most often more bearable than hard mental work. There's nothing like beig 'done' after a hard day of work. After a hard day of mental work you just feel miserable until you fall asleep. If only manual laborers were appreciated (i.e. compensated) as much as mental laborers...
My significant other does manual labor, and it's a good day when they don't want to just come home and fall asleep on the couch and those good days are rare. Even after my worst days of a software dev job, I still have the energy to come home and cook dinner, do some yard work, and other chores.
I will echo your line about wishing manual laborers were better appreciated. I have impostor syndrome, but it's not in comparison to peers in my industry, it's feeling like I don't deserve to earn multiples more then people like my spouse who break their bodies for a pittance.
well, yes, unless after hard day of work, you have more work waiting or, you go to bed worrying if weather will kill your crops, or will you be able to sell them, etc. Farming in particular is much more like running a startup, then it is like office work, where the risk of running business is someone else's problem, and you get your salary at the end of the month no matter what.
