Metaphors and beautiful language don't change the plot. The Great Gatsby can be summed up rather easily: A man named Nick moves to town and is fascinated by his wealthy neighbor, Jay Gatsby. As they get to know each other, he discovers that Gatsby is enamored with his cousin Daisy Buchanan, who is married to a complete asshole. Over time, Nick and Tom both discover that Jay is not old money but rather most likely a man who amassed wealth by participating in fraud.

Tom Buchanan and Jay fight over Daisy, and Tom's side chick is overcome with emotion and is hit by a car. Tom couldn't give a fuck about what happened bc he's a total monster who only cares about money and power. Gatsby takes the blame for the woman's death, and her widower tracks down Gatsby and murders him in revenge.

Long story short: pre-Crash capitalism was an orphan-crushing machine. Gatsby got money to pursue love and ended up dead. Buchanan had money and has little positive emotion toward anyone else in the world. Daisy is also concerned with wealth and prestige and allows herself to be mistreated by her husband and thought about leaving him for a richer man. The narrator is also wealthy, and we see him do the same bad acts he criticizes others for, making him ultimately a hypocrite.
