I have often disliked the practices of Microsoft, and don't think creating benevolent billionaires is the best way to solve the world's problems, but I have to credit the fact that Bill Gates has actually tried to change the world for the better through the Gates foundation.
In comparison, Jeff Bezos's aspiration to travel into space seems to me mawkish (to use the same word as Russell Brand https://www.youtube.com/watch?v=uhMY23kgcKQ).
Jeff Bezos says that space "changes your relationship with this planet, this humanity, it's one earth". It seems to me completely out-of-touch with the reputation of Amazon.
