What's so great about Gatsby?

The great thing about The Great Gatsby is that the characters and their decisions also reflect life in America today. Gatsby, the main character, is good but not that good, like any normal human being in this point in time (unless you're specific people but we won't get into that). Gatsby's okay, I just feel like he tries too hard, you know? Too hard to fall in love, too hard to be so great, and too hard to look accomplished and successful. Nick, the narrator, compliments himself by saying he's one of the most honest people he's ever met. So far, in this book, he's not wrong. Everyone has shown some sort of fake facade that they have, they can't seem to be true to others or even themselves. He seeks to create relationships with dishonest people possibly because he likes to know that he's the better one out of all of them, or maybe to help them realize that they have problems that they should fix. Fitzgerald describes Tom and Daisy in that way because he wants to show that, truly, Tom and Daisy are just reckless people who hide behind their money and social status. They think that they're better than everyone simply because they could do what they desired and get away with it. They're both bad people, and when put together you don't know who's worse. I don't understand why Daisy is so selfish, is it because she grew up with everything she wanted? Why does she only think about herself, she makes herself the victim and hangs everyone out in the dust. I would absolutely disapprove if anyone I knew, especially my brother, dated Daisy. We (or atleast I) didn't grow up like that, getting everything they wanted and getting away with a lot of things, and I wouldn't want anyone being taken advantage by someone like her. The last line of the book: "So we beat on, boats against the current, borne back ceaselessly into the past," describes that no matter how much people try and change whatever happened, we have to keep going with the current and heading forward instead of beating through the currents of the past.
