I also worry about kids in Sudan, and in Yemen, and in other parts of the world. And here’s my problem: we live in a world with nation states. I have borders. You may believe that it’s inherently unfair that a child born in El Salvador has a completely different set of opportunities available and a completely different set of dangers than a child born in the US. And that’s because it is unfair. I can’t fix that for you.”
