I cannot for the life of me understand why the American market keeps going up. Our economy has some real challenges. The infrastructure's falling apart. We're destroying jobs with technology. We are keeping the best and the brightest from around the world from coming to America to create new jobs and create new businesses. All of those things would give you pause to worry about the future.

Unemployment in America today is too high. And part of the reason, unfortunately, is that many companies cannot fill the high-skilled jobs increasingly at risk of going overseas.

Fighting climate change isn't just an obligation we owe to future generations. It's also an opportunity to improve public health - and drive economic growth - in the here and now.

We're paying more for the privilege of getting sick and dying early. Once again, it makes no sense. And once again, no one in Washington is talking about how to fix it.

I don't know why people carry guns. Guns kill people.

You know, Russia today is, what, 200 million people? In land mass, it's probably 50 times the size [of Japan], in natural resources a hundred times the size! Russia's not doing all that badly. The public there - not everybody - but they have things that the West offered, [that] were only available in the West a long time ago.

And because no matter who you are, if you believe in yourself and your dream, New York will always be the place for you.
