I think you nailed it. Disguised as a romantic tale, but in reality much more a tale of “old money” vs. “new money” and the things money (especially ‘new’ money) can’t buy.

Gatsby literally supplied them with alcohol and parties, but was still looked down on by those who never had to work.

Gatsby didn’t just want daisy, he wanted daisy to specifically tell Tom that she is choosing Gatsby over him. That’s not love.

It’s narcissism. And chasing after impossible things and feelings because they require the admiration of others, not because they desire the goal itself.

Gatsby disguised his success as a motivated romantic journey from rags to riches, much like this book disguised itself as a romantic novel.
