coined 1931 by James Truslow Adams (1878-1949), U.S. journalist and popular historian (unrelated to the Massachusetts Adamses), in "Epic of America." [The American fantasy is] that dream of a land where life must be better and richer and fuller for everyone, with chance of each relating to capability or success. It's a difficult fantasy for European top classes to interpret properly, and way too many people ourselves have cultivated weary and mistrustful of it. It's not a dream of motor vehicles and high wages simply, but a dream of social purchase in which each man and each girl shall be able to attain towards the fullest stature which these are typically innately able, and start to become acknowledged by other people for what these are generally, whatever the fortuitous circumstances of delivery or position. [Adams] Other people purchased the term as they begin to.
the extensive aspiration of Americans to call home much better than their moms and dads did
