How many more astrophysicists would we have if the current wealth of the top 10 billionaires went to our educational system and bringing people out of poverty?

How many more astrophysicists would we have if the current wealth of the top 10 billionaires went to our educational system and bringing people out of poverty? Sending billionaires into space accomplishes nothing that the rest of humanity can benefit from, and actually would do a good bit of damage to our future. Sure, the tech will get better, but it will be patented and upcharged in a way similar to our pharmaceutical industry, only with fewer regulations. Space is too important a frontier and space exploration is too important an endeavor to squander in this way. We need NASA in space, not billionaires.
