… there will always be a segment of the population that will only act when incentivized

I’d argue that this is true of all the population but with the stipulation that “incentives” do not need to be monetary. I completely agree that capitalism is not human nature and feel that we’ve essentially brain-washed people to believe that money and material possessions are the reward when in fact it’s all the other things in life that actually matter. I believe that this thinking, which had lots of good reasons for existing during times of scarcity and paucity of resources, can be undone eventually. I think in a post-scarcity world (I’d argue we’re there) where it is normal for people to live fulfilled lives in significant comfort free from financial and work stress those few people who can’t shake the need to competitively accumulate will be rare indeed.

Until then we have a huge problem: we have too much highly efficient prosperity for capitalist models to make any sense at all.

Yes, I’m thinking of fully automated luxury communism.
