the people can rise up against the capitalists to stop them from poisoning our only habitat we are all wholly dependent upon
Are you ignoring all the labor these "capitalists" and their workers do to provide you the goods we all wholly demand upon? All of this is done by social cooperation between both of them by voluntary association.
We can stop the self-destructive madness of demanding infinite growth carved out of the ass of a finite world.
This would work if the price system would actually work as intended (free from the intervention of the State) to distribute all the scarce resources in a free-market setting.
Greta is doing the right thing in the face of Armageddon
By wanting the Monopoly of Violence to step in? To call the international organizations (spoilers: they don't care about us) to intervene in foreign countries?
Almost everyone else will either continue begging the sociopathic oligarch polluters to stop
They can actually do that because of the existence of "common goods" and of the monopolical privileges granted by the same State, such as subsidies, regulations discreetly affecting SMEs, the lack of enforcement of private property to protect those "common goods", etc.
but those are usually the same people that get angry at others for claiming the “free capital market” isn’t the cure for the many self-inflicted human crises caused by the “free capital market.”
On the contrary; they love subsidies, they love intellectual property, they love FIAT money, they love the monopolical privileges: basically, their activities depend entirely on the mere existence of corporatocracy.
