A week after the 236th anniversary of the birth of the United States — which was squalling to the world in its very first utterance that all men were created equal and endowed with unalienable rights — the essence of our politics is still about who are those people who are self-evidently equal and inherently vested with those rights.

Over the subsequent two-plus centuries, we've invoked the spirit of our primal shout every time we've expanded our definition of equal men — when we moved to popular elections, abolished slavery, gave women the vote, enacted civil rights legislation, and today, when gays and lesbians are winning the equal status and unalienable rights that heterosexual Americans take for granted.

But the author of our founding declaration was concerned with more than legal equality. Thomas Jefferson envisioned a nation of yeoman farmers (and, to be sure, slaveholders like himself) and wanted it to remain chiefly rural to avoid the concentration of wealth and power that would come if the nation urbanized and if finance grew into a dominant sector.
