Obama is Brother's Keeper and Sister's Keeper

Here's how Barack Obama defined the American Promise in Denver last week:

Each of us has the freedom to make of our own lives what we will, but that we also have the obligation to treat each other with dignity and respect.

The market should reward drive and innovation and generate growth, but that businesses should live up to their responsibilities to create American jobs, look out for American workers, and play by the rules of the road.

Government cannot solve all our problems, but what it should do is that which we cannot do for ourselves - protect us from harm and provide every child a decent education; keep our water clean and our toys safe; invest in new schools and new roads and new science and technology.

Our government should work for us, not against us. It should help us, not hurt us. It should ensure opportunity not just for those with the most money and influence, but for every American who's willing to work.

We are responsible for ourselves, but that we also rise or fall as one nation; the fundamental belief that I am my brother's keeper; I am my sister's keeper.
