Bezos should put his billions in public libraries
I would much rather billionaire types take on large issues that governments don't want to touch, like space flight or specific diseases in foreign countries, than something already in service like libraries. Maybe I just have a bias due to having a library just up the street from where I live currently, but I have never not had access to an adequate library in my life time, and only see room for marginal diminishing returns in improving them.
