There's a whole lot more to unpack in the film. For one, only Ken had an "I want" song ( https://en.wikipedia.org/wiki/%22I_Want%22_song ). Only Ken had a real longing and unfulfilled need. Only Ken goes through a real transformation. Just like Greta cut-up the timeline in Little Women, she cut-up the timeline of the Ken Musical. It's Ken's movie, it's Ken's story, told from the limited-POV of Barbie with dramatic irony. I could re-edit the timeline and scenes and make it obvious. The big speech is more the "conservative" critique of Glamor Mag Feminism, than feminism.
