Agreed with the general idea that after a certain threshold billions need to start going back into society, if not in the form of taxes then directly to areas of need.
Same goes for large corporations. After a certain point, billions need to start flowing into something other than gobbling up the competition, stock buybacks, mergers, and space projects.
I wouldn't be as generous as you though. For personal wealth, I'd draw the line at about 10 billion, after that you can give it to the government and let them squander it or you can go direct to the source.
As for corporations. 25 billion give or take, that's enough to do everything you need to do. All the excess after that, again you can cough it up to uncle sam or go directly to an area of need with it.
Do we really need to worry about space life thousands of years from now when we have hunger, cancer, and environmental issues right now? I say let's take care of this planet, it's people and issues before we go fu** up the galaxy and other planets.
I think that's how the health care issue can be greatly helped.
Gates, Zuckerberg, Google, Amazon as a company and Bezos individually, Buffet, Berkshire, etc...need to start putting their excess into the problems of today.
Each of those individuals and companies can all afford to cut off their personal and company wealth after a certain threshold then build and fund dozens of hospitals, clinics, doctors offices, etc...
I know they all give to charity and have foundations, but I feel like that creates a lot of middle people. The Giving Pledge that Gates started is all great, but I'd like to know where all that money is going? Is it building free health care services, is it doing anything about the homeless crisis, how about opioid crises, and on and on with all the problems we have.
Every rich American titan being obsessed with Africa has always been a head scratcher to me as well. Christ, we have hungry black, white, Latino, etc kids and homeless shanty towns right here in this country. Let's clean up our house, and get our shit straight and then go help the world.
