Thanks for the quick history lesson. But..."When farming came in." Farming "came in" 6,000 years ago when recorded history began. Are you suggesting that without farming we cannot "gather" or "perform physical tasks"? I guess that's another reason to love farming! And with the industrial revolution people go to production lines and "mental work". Huh? What's "mental work"? Working on an assembly line is mental work? You ask where humans move, the answer is that we figure it out. We think and we innovate and we find new ways to do things. We might program the robot, or grease it's levers and gears, or we do something we've never thought of before. We'll do "mental work" to figure out what to do next. Where are the new jobs coming from? We innovate and build and come up with ideas that no one has ever thought of before. Imagination grows and builds. Want a wonderful thought exercise in economics and entrepreneurship and innovation.

I think you could just as easily argue that money is always available to anyone willing to put in work and effort. And today, you could argue that it's more accessible than ever. We hear a lot about the "unbanked", but cryptocurrency and the internet has unlocked financial world's for many, many people. Even those without internet access...they often have access to a mobile phone which can be used to interface with financial systems. Effort, work, production, ingenuity have always been valued and still are human capital with which anyone can earn.
