You're talking about something completely different, and casting the question in zero-sum terms when it is not fundamentally a zero-sum question.
If in the future a machine is built that can build other machines that can build shelter and grow food and provide medical care for humans, assuming we don't run out of space, the people who decide not to work (or, possibly, to work on something "non-productive" like art) are not "taking from the productive". "The productive" can completely ignore them, and dance Moloch's tune to their hearts' content on another planet somewhere far away.
Halfway to that, in a theoretical society where those needs can be satisfied for the entire population by a relatively small workforce, there's no fundamental reason the members of that workforce can't be incentivized with economic privilege. There's also no fundamental reason that people who do want to work at solving new problems can't do so, whether their reward is economic or personal and intangible (or both).
People stuck in soul-sucking jobs in our make-work services economy aren't being productive—they're just hamsters in a wheel, printing money for the oligarch class via our insanely unsustainable consumer economy. All of it is stupid bullshit and all of it will inevitably fall over, and industrial society with it, if it doesn't change.
> All attempts turn into coercion and atrocity, because it's only natural to want to be rewarded for one's work, and the alternative is slavery.
Or, alternately, because sociopaths always rise to the top and become jealous of their power and position, and we're only just now reaching the point where something like my second paragraph is technologically feasible. Lots of "collectivist" models assume the necessity of a "means of production" powered by labor, but in a sufficiently advanced society, that need for labor will be diminished or outright deleted.
> It really amazes me how many people in tech push for a social system that would have prevented tech emerging in the first place and that would have led for lower status for themselves. It's fundamentally unserious.
Temporarily embarrassed billionaires, that's us.
