A world that allows billionaires/trillionaires is inherently and unfair world.

For every billionaire, there are untold thousands of people in poverty. How will this raise the living standards for the poorest? It won't because the rich control the government, so no taxes for the rich, who won't give up their money without a fight. So let's please dispense with somehow describing the profit raping of space as a boon to all mankind.
