You're assuming that everyone's purpose is to earn passive income.

There are plenty of people whose purpose is just to do "good honest work" as some people call it. Some people enjoy seeing things being built of their own hands, and enjoy being in the sunshine doing a job that keeps them physically fit while they do it.

And some of the worst/most dangerous of that work - such as being a miner - will eventually be obsolete.

There are people who have the options and choose what seems to most to be a working class profession. I met a wealthy woman in her 50s who up and chose to be a long distance trucker.
There's also that 50+ guy who decided to work at Starbucks and it is his life work. He enjoys his work.

If my partner could do any profession he wanted, in this day and age, he'd be a *shepherd*.

Freed from wage slavery, would people choose to dig ditches? Some think MORE people would.

Ursula LeGuin's book "The Dispossessed" talks about an engineered utopia, she addressed this very problem... the theory posed in the book was that once freed from "wage slavery" most people wouldn't mind signing up to do the necessary manual labor/maintenance tasks for a few hours a week. Since everyone was expected to contribute this (and this came via peer pressure, not government enforcement), no one person had to make it their life work UNLESS THEY WANTED TO (and there were plenty that wanted to).

Mind you, the society also was not a capitalist one, and had its own issues, but I'm just saying that there is other thinking out there about who could do the "♥♥♥♥♥ work" of civilization.
