There's also the fact that "they" aren't all one and the same persons with the exact same worldview and interests.
You might say "but why not use just 1% of that GDP on making sure the rest of humanity lives in at least minimal comfort"? But clearly -- we already choose not to do that today. 1% of the GDP of the developed world would be more than enough to solve many horrifying problems in the developing world -- what we actually give is a far smaller fraction, and ultimately not enough.
Of course there is always the issue of “demand”—of keeping the factories humming, but when you are worth billions, your immediate subordinates are worth hundreds of millions, and all of their subordinates are worth a few million, maybe you come to a point where “lebensraum” becomes more valuable to you than another zero at the end of your balance?
When AI replaces the nerds (in progress), they become excess biomass. Not talking about a retarded hollywood-style apocalypse. Economic uncertainty is more than enough to suppress breeding in many populations. “not with a bang, but a whimper”
If you know any of “them”, you will know that “they” went to the same elite prep schools, live in the same cities, intermarry, etc. The “equality” nonsense is just a lie to numb the proles. In 2025 we have a full-blown hereditary nobility.

The West is not The World. There are over a billion Chinese, Indians, Africans…
Words mean things. Who said tree hugger? If you are an apex predator living in an increasingly cloudy tank, there is an obvious solution to the cloudyness.
Don't forget fertility rate is basically stagnant in the West and falling globally, so this seems like a waste of time considering most people just won't breed at all.
