We cannot erect walls between the north and the south, between the rich and the poor. We need to make sure that we have an equitable world, where every human being has the right to live a decent life, the right to live a life free from fear, the right to be able to send his kids to have education, the right to have Social Security in their old age. If you do that, I think the insecurities we feel — the extremists that we are seeing — will drop absolutely dramatically.
