In “Democracy in America” by Alexis de Tocqueville in 1831, he said in the first phrases:
<em>“Amongst the novel objects that attracted my attention during my stay in the United States, nothing struck me more forcibly than the general equality of conditions. (…) The more I advanced in the study of American society, the more I perceived that the equality of conditions is the fundamental fact from which all others seem to be derived, and the central point at which all my observations constantly terminated.”</em>
