The races are like America's children. White people are the firstborn, so they were Dad's favorite. Black people are the second kids, the abused ones, so they still hate Dad. Latinos are the third, caught in the middle and always trying to make peace between the other siblings. Asians are the youngest, and get good marks in school, but basically are just trying to keep their heads down and not get involved. And Native Americans are the old uncle who owns a house and everyone else in the family was like, "He's not using that! Let's move in!

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.
