We need a new, deeper appreciation of the ethnic histories of the American people, not a reduction of American history to ethnic histories.

America isn't breaking apart at the seams. The American dream isn't dying. Our new racial and ethnic complexion hasn't triggered massive outbreaks of intolerance. Our generations aren't at each other's throats. They're living more interdependently than at any time in recent memory, because that turns out to be a good coping strategy in hard times. Our nation faces huge challenges, no doubt. So do the rest of the world's aging economic powers. If you had to pick a nation with the right stuff to ride out the coming demographic storm, you'd be crazy not to choose America, warts and all.
