Black children, white children, Latino children. America is becoming more diverse, it's becoming more tolerant as a consequence there's more interactions between groups. There are going be tensions that arise.

I think one of the tragedies of the civil rights movement was because the civil rights movement became so court-focused, I think that there was a tendency to lose track of the political and community organizing, and activities on the ground, that are able to put together the actual coalitions of power throughout which you bring about redistributive change. And in some ways, we still suffer from that.

When we don't pay close attention to the decisions made by our leaders, when we fail to educate ourselves about the major issues of the day, when we choose not to make our voices and opinions heard, that's when democracy breaks down. That's when power is abused. That's when the most extreme voices in our society fill the void that we leave. That's when powerful interests and their lobbyists are most able to buy access and influence in the corridors of power - because none of us are there to speak up and stop them.

I look forward to hosting Prime Minister Lee [Hsien Loong], whose friendship and partnership I appreciate very much and with whom I've worked throughout my administration.

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.
