e exchange of ideas, that liberty unlocks a people’s full potential.

It’s why our workers are among the most productive, why our inventors and entrepreneurs hold more patents than any other country in the world, why we are reinvesting in the fundamental sources of our strength -- education, infrastructure, innovation, and why President Obama and I are so confident that America will weather the current economic storm and emerge even stronger, just as we always have in past economic crises, and why there’s no reason why China cannot tap into the same source of strength.
