I don't know much about social studies and the like, so I ask this in earnest. How is Bezos having $100b good for American citizens?
Well, he spends a chunk of it on space exploration/exploitation technology, that could benefit all of us immensely. He pushes a lot of technological boundaries and is one of the few companies that could push a major initiative through to completion, like drone deliveries, robotic trucks, stuff like that.
