The closest thing to that sentiment comes from her statement about "wanting her daughter to be a beautiful little fool," which is often misquoted as "wanting her daughter to be a fool."
This line appears in Chapter 1, when Daisy is talking to Nick Carraway about her daughter, Pammy:
> "I hope she'll be a fool - that's the best thing a girl can be in this world, a beautiful little fool."
It's important to understand the context of this statement:
* It's said in a moment of sadness and disillusionment. Daisy is reflecting on the difficulties of being a woman in a society that values beauty and innocence above all else.
* She's not actually advocating for ignorance. Instead, she's acknowledging that a woman's beauty and naivete can be her shield in a world where she might be exploited otherwise.
* It's a cynical comment on the limitations placed on women. Daisy is expressing her awareness of how women are expected to play a specific role, one that prioritizes superficiality and naivety.
While Daisy's words might seem harsh, they're a reflection of the societal pressures she faced as a woman in the 1920s.
