Six figure blue collar jobs are not super common in the US.
You may work yourself to the bone but pretty much anybody in the US can make a killing.
when you're working 16 hours a day 7 days a week you don't really notice much outside of the factory floor anyway. Whether it was remote or in Manhattan you wouldn't feel the difference as you do nothing but work. I was working ~112 hours a week when I was in Alaska.
And the settlers nearly starved the first few winters in every colony despite that.
And in pre-industrial times, when 70% of the population were farmers, land was a direct, and immediate proxy for wealth. Wealth that stayed with you and your family. You were the owner, instead of some shitty sharecropper for a landlord.
[1] I mean, aside from the natives.
As for land being a proxy for wealth that stayed with you, that worked out OK as long as there was lots of land for people to grab up and claim as their own (or take from some natives who don't have the weapons technology to fight back well). And it's the reason people colonized North America: because all the land in Europe had been claimed by some shitty landlord. These days, that's all gone: now you're stuck living with a shitty landlord again, and there's no new continents left to colonize, so we need to come up with a better economic system.
