The real thing destroying the environment is not capitalism, but globalization, combined with overpopulation and automation. Elon and Bezos couldn't have so much wealth if technology didn't allow them to sell their products to the entire world of 8 billion people.

And individualism is actually correct, because all pleasure and pain (and therefore, any semblance of morality) can ultimately only be appreciated and judged from the perspective of individual sentient beings.

Whereas a preoccupation on "community" is actually bad, because it crushes the individual - for example, when Mao caused the deadliest famine in human history by giving rice to other countries when his own population was starving.

And the West is not immune to this either. The fact that European men marched en masse to their slaughter during WWI is the same type of cummunity-centric lunacy, which crushes the individual in the name of "King and Country".

The trick is to get individuals to collaborate in such a way that they create a world that they can all enjoy, individually. This requires, more than anything, an understanding of game theory.

And we need to use our knowledge of game theory to find a system that auto-corrects society to maintain some level of equality, not of wealth per se, but of power. Because an aggregation of power is the thing that ultimately causes some people to capture all the wealth.

No version of communism has ever solved this problem, because there's always somebody at the top who has all the power - which is no better than what capitalism has been able to achieve. But at least capitalism has two routes to power - via the market, and via the government. Whereas the only route to power in communism is via the government. Which makes it more tyrannical.
