The United States does not have a monopoly on crazy people. It's not the only country that has psychosis. And yet we kill each other in these mass shootings at rates that are exponentially higher than anyone else. Well, what's the difference? The difference is that these guys can stack up a bunch of ammunition in their houses, and that's sort of par for the course.

Where we get into problems, typically, is when our personal religious faith, or the community of faith that we participate in, tips into a sort of fundamentalist extremism, in which it's not enough for us to believe what we believe, but we start feeling obligated to, you know, hit you over the head because you don't believe the same thing. Or to treat you as somebody who's less than I am.

I believe that the free enterprise system is the greatest engine of prosperity the world's ever known.

Keep in mind that, when I came in, we had had a crisis that was the worst we've seen since the 1930s, and working with people like Chancellor Merkel, working with the G-20 and other institutions internationally, we were able to stabilize the financial system, stabilize the US economy and return to growth.

That is the story of our history - whether it's the pursuit of prosperity for our people or the struggle for equality for all of our citizens, our commitment to stand up for our values abroad, and our sacrifices to make the world a safer place. Let us remember that we can do these things not just because of wealth or power, but because of who we are. One nation under God, indivisible, with liberty and justice for all.

America must always lead on the world stage.

There are certain things we can only do together. There are certain things only a union can do. Only a union could harness the courage of our pioneers to settle the American west, which is why President Abraham Lincoln passed a Homestead Act giving a tract of land to anyone seeking a stake in our growing economy.
