Sustainable communism is literally what Marxism and these SDG's are all about.

The end goal of Marxism is to destroy the current system and then force and brainwash everyone over and over to do the Marxist version of "the right thing," aka "The Great Reset," until society reproduces mankind so that they live communism on their own without the state forcing them into it. Hence "saving" all of mankind.

You'll notice every time a socialist steals your money and does something with your money, whether they be a Democrat or a Republican, they take all the glory for themselves.
