Communism, capitalism, or even fascists could strive to survive. It's only a question of informing them that they have a way to become internally consistent. See my web site for more about the use of durability to conserve. And as sometimes stated, a nearly always implied assumption, was solidarity with the oppressed and exploited, especially the workers and peasants of Africa, Asia, and Latin America.
Fascists are the worst form of pollution and waste.
We can start cleaning up the planet by getting rid of the fascists, not offering them advice. We can't wait for the 2nd coming of anyone. We can propose ways to fix existing systems, of whatever stripe. My I repeat what I believe is a positive suggestion.
