“Could it be that Americans are a restless people, a mobile people, never satisfied with where they are as a matter of selection? The pioneers, the immigrants who peopled the continent, were the restless ones in Europe. The steady rooted ones stayed home and are still there. But every one of us...are descended from the restless ones, the wayward ones who were not content to stay at home. Wouldn't it be unusual if we had not inherited this tendency? And the fact is that we have.”
