I'm not trying to be mean. You [ Nicholas Kristof] have written about climate change. You're really concerned and you've thought a lot about the suffering of people in other countries. It doesn't seem like you have thought that deeply about the suffering of your fellow Americans. You don't have the solutions say as you do for global warming. And my question is: Isn't it always easier for the elites to identify with abstractions or poor people in other countries and kind of ignore their own country men. I have noticed this. Have you noticed that?
