We have an alliance that was forged more than a half century ago, and strengthened by shared interests and democratic values. Our people share ties o… - Barack Obama

I learned to slip back and forth between my black and white worlds, understanding that each possessed its own language and customs and structures of meaning, convinced that with a bit of translation on my part the two worlds would eventually cohere.

There are any number of reasons America emerged from its humble beginnings as a cluster of colonies to become the most prosperous, most powerful nation on earth. There is the hard work, the resilience, and the character of our people. There is the ingenuity and enterprising spirit of our entrepreneurs and innovators. There are the ideals of opportunity, equality, and freedom that have not only inspired our people to perfect our own union, but inspired others to perfect theirs as well. But from the very start, there was also something more. A steadfast commitment to serve, to fight, and if necessary, to die, to preserve America and advance the ideals we cherish. It’s a commitment witnessed at each defining moment along the journey of this country. It’s what led a rag-tag militia to face British soldiers at Lexington and Concord. It’s what led young men, in a country divided half slave and half free, to take up arms to save our union. It’s what led patriots in each generation to sacrifice their own lives to secure the life of our nation, from the trenches of World War I to the battles of World War II, from Inchon and Khe Sanh, from Mosul to Marja.

And in fact, at every moment of economic change throughout our history, this country has taken bold action to adapt to new circumstances and to make sure everyone gets a fair shot. We set up worker protections, Social Security, Medicare, Medicaid to protect ourselves from the harshest adversity. We gave our citizens schools and colleges, infrastructure and the Internet -- tools they needed to go as far as their effort and their dreams will take them. That’s what middle-class economics is -- the idea that this country does best when everyone gets their fair shot, everyone does their fair share, everyone plays by the same set of rules. We don’t just want everyone to share in America’s success, we want everyone to contribute to our success.
