[Jeb Bush] could, as I describe it, run the railroad.[John] Kasich could run the railroad. Hillary Clinton can run the railroad. Running the railroad is the most important thing. You have got 4 million employees; you've got to make the system work, and it doesn't work very well.

People vote against their own interests that all the time. But when you do the polling in the U.S., it has gone from less than 50 percent who thought climate change was real to 70-odd percent. And if you listen to the Republicans in Congress, they used to say, "Oh, climate change doesn't exist." Then they switched to "Well, it exists, but it's not man-made," to "Well, I'm going to address the issue." Why? Because when they go home, the local constituent says, "Wait a second. What are you talking about? We just had a flood. We haven't had rain in a long time." They can't get away from it.

I think if you look at people, whether in business or government, who haven't had any moral compass, who've just changed to say whatever they thought the popular thing was, in the end they're losers.

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.

Design does matter. And not necessarily in a way that people realize. A lot of what you do, people take for granted - that a park has always been here, that a bicycle lane has always been there, that the street is safe or clean.

My personal view is, why don't you get out there and try to do something about the things that you don't like, create the jobs that we are lacking, rather than just yell and scream. But if you want to yell and scream, we'll make sure you can do it.

I'm trying to change the culture in New York City; that's hard enough!
