Six decades ago, as Mao's Communists seized power, the question in Washington was, 'Who lost China?' Now, as his capitalist descendants stand astride the world stage and Washington worries about decline, it seems to be, 'Who lost America?'

Much of our national debate proceeds as if China and America were locked in a zero-sum game in which one's loss is precisely the other's gain.

From the right, you get demagogues shouting about brown-skinned anchor babies and clamoring to deport the undocumented. From the left, you get advocacy for the oppressed but otherwise, when it comes to national civic identity, mainly silence.

At the heart of our public morality is the idea that he who gives generously is most virtuous and morally praiseworthy; that there is no greater citizen than she who sacrifices; and that there is no greater measure of worth than contribution. These are values we can be proud of. After all, there is no moral system or religion on earth where the guiding ethic is grab more for yourself.

Imagine filling a college with the first 1,000 students to get perfect SATs. Whatever the racial composition of that class would be, the notion seems absurd because we know that college in America is supposed to be about creating citizens and leaders in a diverse nation.

Love of country cannot be a supersized version of individual narcissism. True love of country-of this country-is love of our children, of a creed that promises them a better life before it promises us anything, and embraces the sacrifices needed to make that better life. True love of country is giving ourselves to a cause and a purpose larger than ourselves. And that cause is to make liberty worth having, to make the pursuit of happiness deeper than the quest for personal pleasure, and to leave a legacy of progress and possibility.

To be sure, the United States has profound problems, not least our faltering educational and physical infrastructure.
