America is a nation founded on the basis of open borders. Since the country gained independence, millions of people have braved perilous oceans, scaled deadly mountain ranges, and crossed rapid rivers to become a part of the first genuinely multicultural society. Some of these cultures blended together, while others resiliently preserved themselves. Yet all have contributed to the conglomerate we know as the United States of America.

This diversity has its effects; many of things America calls its own are not actually so—they’ve just been perfected here. Pizza, football, the political campaign, and in the culture of juice, zinfandel.
