Considering the likelihood of success in starting an electric car company and a rocket company, I'm pretty sure Musk did not mind investing, not just his money, but his time, in making everyone, on the whole, more prosperous.
Someone interesting solely in making money would probably have chosen other ventures.
Giving their money away to make everyone on Earth rich would not work , but if it did, I think it likely that they would. First off, either one of them could likely start from zero and end up wealthy again. Also, their wealth is tied up in their ventures, and those ventures are the wealth they are providing, although I understand that not eveyone will see them as beneficial. I don't particularly see Amazon as a net benefit necessarily.
I don't think they are that different in mindset from Bill Gates, and he seems intent on giving away his money in the most efficacious way he can find.
