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.

Every one of us is equal. Every one of us has worth. Every one of us matters. And when we respect the freedom of others -- no matter the color of their skin, or how they pray or who they are or who they love -- we are all more free. Your dignity depends on my dignity, and my dignity depends on yours. Imagine if everyone had that spirit in their hearts. Imagine if governments operated that way. Just imagine what the world could look like -- the future that we could bequeath these young people.
