What incentive do I have in not-that-system to be a cooperative, generous hard worker that practices collectivism instead of a power-addicted exploitative ambitious business magnate?
Collectivism is overrated and unnecessary. I'm a misanthrope and I don't want to live in a collective society, I want to live in a society where I can get away from other humans and keep to myself. Taxes and laws are enough to keep society civil and functional; going beyond that is imposing your own personal beliefs on everyone else, like a theocracy or dictatorship.
This is a pretty hilarious take IMO. Cooperation is literally the only reason humans are the dominant species on the planet. But sure, "overrated and unnecessary".
There's a difference between collectivism and cooperation. I contrast collectivism with individualism; i.e. valuing the collective over the individual vs valuing the individual over the collective. I want to live in an individualist society, not a collectivist one.
^- is another awfully slanted question.
