American Dream - Wikipedia:

"The American Dream is the faith held by many in the United States of America that through hard work, courage, and determination one can achieve a better life for oneself, usually through financial prosperity. These were values held by many early European settlers, and have been passed on to subsequent generations. What the American Dream has become is a question under constant discussion, and some believe that it has led to an emphasis on material wealth as a measure of success and/or happiness."
