It may be something that future generations are more open to, but I am pretty confident that for the foreseeable future, using the argument of nondiscrimination, and "Let's get it right for the kids who are here right now," and giving them the best chance possible, is going to be a more persuasive argument.

It is my judgment that had I spent the first two years trying to get a single-payer system, all those folks who now have health insurance that didn't have it would still be uninsured. And those are millions of people whose lives are impacted right now.

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.

We forget now, but during his life, Dr. King wasn't always considered a unifying figure. Even after rising to prominence, even after winning the Nobel Peace Prize, Dr. King was vilified by many, denounced as a rabble rouser and an agitator, a communist and a radical. He was even attacked by his own people, by those who felt he was going too fast or those who felt he was going too slow; by those who felt he shouldn't meddle in issues like the Vietnam War or the rights of union workers.

There are legitimate concerns and anxieties that the forces of globalisation are leaving too many people behind - and we have to take those concerns seriously and address them. But the answer isn't to turn inward and embrace protectionism. We can't just walk away from trade.

The more we can encourage entrepreneurship, particularly for young people, the more they have hope. That requires some reforms in these [African] governments: rooting out corruption, increased transparency and how government operates, making sure that regulations are not designed just to advantage elites, but are allowing people who have a good idea to get out there and get things done.

There’s only one thing we can be sure of, and that is the love that we have -- for our children, for our families, for each other. The warmth of a small child’s embrace -- that is true. The memories we have of them, the joy that they bring, the wonder we see through their eyes, that fierce and boundless love we feel for them, a love that takes us out of ourselves, and binds us to something larger -- we know that’s what matters. We know we’re always doing right when we’re taking care of them, when we’re teaching them well, when we’re showing acts of kindness. We don’t go wrong when we do that.
