Because capitalist doctrine insists that humans are inherently greedy, self-centered and competitive, its believers cannot imagine any solution to our problems that isn't driven by greed, selfishness and competition. The idea that we can transcend our propagandized conditioning, our cultural mind viruses and our egoic thought patterns enough to move from our competition-based system into a collaboration-based one looks ridiculous to them, because they believe our nature can only ever be at war. At war with each other, and at war with our ecosystem. 

To a thoroughly capitalism-indoctrinated mind, the idea that we can transcend our self-destructive, exploitative, ecocidal patterning and move into collaboration with each other and with our ecosystem to create a healthy, harmonious world looks like childish nonsense. So instead they promote the far more mature and realistic idea that our world will be saved by greedy, union-busting tech oligarchs like Elon Musk.
