I agree, the billionaires are jerks. The idea of humans inhabiting space or any other planet in our solar system is an absurd fraud. I cannot imagine any elites being willing to leave this gorgeous planet and go live in vacuous space. More likely they would want to ship the "useless eaters" there to get rid of them or to be slaves in mines, all sold with flowery utopian sales pitches of course. But I am not convinced that the "human heart is desperately corrupt" which I think is an overlay imposed by the psychological consequences of capitalism over the last 500 years. Lets end capitalism and create the heaven on earth we all know if possible. Can the world unite around the common enemies of climate change, pollution, poverty, and the unjust management of of our economy. As you make clear, it is a matter of justice.
