Literrally, what is the "American Dream" ?

This term was started by writer James Truslow Adams in his book "Epic America" written in 1931. In it he states that the American Dream is "that dream of a land in which life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement. It is not a dream of motor cars and high wages merely, but a dream of social order in which each man and each woman shall be able to attain to the fullest stature of which they are innately capable, and be recognized by others for what they are, regardless of the fortuitous circumstances of birth or position."
Although the term was first used in the 1930's, it seems that even our founding fathers had some idea of how this "dream" would be defined. Thus, the Declaration of Independence was put into place to protect the right to a "dream" by all. It was the first time a document like this had been produced favoring the common man over the elite, as no other nation had ever written something like it. "…held certain truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are life, Liberty and the Pursuit of Happiness."
