The American Dream is rooted in the Declaration of Independence, which proclaims that "all men are created equal" with the right to "life, liberty, and the pursuit of happiness." The meaning of the "American Dream" has changed over the course of history and includes both personal components and a global vision.
Historically the Dream originated in the mystique regarding frontier life. As John Murray, 4th Earl of Dunmore, the colonial Governor of Virginia, noted in 1774, the Americans "for ever imagine the Lands further off are still better than those upon which they are already settled". He added that, "if they attained Paradise, they would move on if they heard of a better place farther west".
