Donald Trump understands sense of belonging. And a lot of people think globalization, any time you make any particularity, you're sort of offending some other group. And a lot of people in this country think they belong to America anymore, and he at least appeals to some sense of belonging.

I think the twenty-first century happened, basically. That this century started on 9/11. And basically, it's been a century of counter reaction to globalization and the meritocracy.
