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.
