What I consistently say to young people - I say it in the United States, but I'll say it here in Germany and across Europe: Do not take for granted our systems of government and our way of life. I think there is a tendency, because we have lived in an era that has been largely stable and peaceful, at least in advanced countries, where living standards have generally gone up, there is a tendency I think to assume that that's always the case.

Whether our forebears were strangers who crossed the Atlantic or the Pacific or the Rio Grande, we are here only because this country welcomed them in and taught them that to be an American is about something more than what we look like, or what our last names are, or how we worship.

Black churches minister to social needs out of necessity.

We do want people to know if in fact we learn of an incident that's focused on a particular city.If we learn of long-term planning, that's focused on a particular industry or infrastructure. And so we feel we have an obligation to let people know if we have information of a credible threat or not.

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.

Just as black anger often proved counterproductive, so have these white resentments distracted attention from the real culprits of the middle class squeeze - a corporate culture rife with inside dealing, questionable accounting practices, and short-term greed.

For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies. So let us mark this day with remebrance, of who we are and how far we have traveled.
