I don’t know much about George Soros, but my world and the world of the Koch brothers cross at multiple points (not at a personal level). I disagree with a lot of their politics, but if I grew up as they did, I can’t say I would be different. A few decades of business experience and empirical evidence say the Koch brothers are very good businessmen and also family men. Maybe they realized that if they want to leave their vast fortune to their heirs, there must be an inhabitable planet for those heirs to live on. One can hope!
