"The rich individuals are increasingly hoarding everything. If the billionaires want to go to space, they could at least leave their money on Earth to solve the critical Earthbound problems. We now have an estimated 2,775 billionaires with a combined net worth of around $13.1 trillion. I have it on good authority that you don’t need more than $1 billion to live comfortably. Even if every billionaire kept $1 billion, that would leave around $10 trillion for ending hunger, poverty, and environmental destruction. We should be taxing the vast and rapidly growing billionaire wealth to help finance a civilized world."
