You don’t need to end capitalism to help the climate. Just properly regulate it.
Except that politicians (i.e. those that would be doing the regulating) all have a price, and for oil barons no price is too high; and bribing is still magnitudes cheaper than stopping the destruction of the environment.
It’s a tool just like every other economic system, and shouldn’t be hoisted to a higher pedestal.
If it’s not objectively better nor special, why not try something more equitable that doesn’t siphon 99% of all resources to the aristocracy elite and leaves everyone else fighting for the crumbs?
Why keep using a system that prescribes that the hungry should starve if they can’t afford food even though we already produce more than enough to feed the whole planet?
