>Other billionaires are working on some of the problems on your list, too, if that makes you feel better. The most prominent one being Bill Gates. He's working on the "we lose millions a year to disease" portion of your list. Do you hate on Bill Gates because he isn't solving world peace ("fighting wars" on your list)?
Relying on the goodwill of billionaires is a problem.
>We need to push forward now to have a chance.
We need to get our house in order now to have a chance. I don't know how that isn't obvious.
