Capitalism can only exist with continual growth or in Marxist parlance “accumulation of capital.”
Socialism is about a steady-state and zero-growth economic system…in Marxist terminology “simple reproduction”
You want to end the threats to the environment then it is partly your choice…continue tinkering with palliatives proved to have failed in the past, or begin trying to change to a new economic system based upon the production for use and not production for profit.
We can provide abundance for all in a sustainable way. Almost a billion suffer from hunger yet already today we can’t feed everybody.
Tell me why people die from deprivation amid plenty. Tell me why people die from curable and treatable illnesses.
If you don’t think it is capitalism or don’t think capitalism can be replaced tell me why. Much more fruitful to have a real dialogue than posting a cryptic comment.
