What does the green light mostly symbolize in the Great Gatsby

The Green Light, situated at the end of Daisy's East Egg dock and barely visible from Gatsby's West Egg lawn, the green light represents Gatsby's hopes and dreams for the future. Because Gatsby's quest for Daisy is broadly associated with the American dream, the green light also symbolizes that more generalized ideal.

Francis Scott Fitzgerald, author of "The Great Gatsby", a novel about the downturn of the "American Dream" in the 1920s, but overcasted by a love story between a man and a woman, also exposing the snobbishness and disdain of the American Aristocracy.

Fitzgerald makes "The Green Light" a symbol for "Love and Wealth", especially Gastby's craze with it; it's also a representation of people's greed for money, their hopes and dreams.
