The most interesting thing about the Barbie movie is Ken's bloodless revolt against the Longhouse.
He is an exaggerated western man in the 21st century. Anxious, confused, chasing women who don't care about him.
Ken starts off as the feminist's ideal man. A totally subservient man with a desire for Barbie that is not even sexual, it's just programming. He does not know why he wants to sleep over, he just knows it's something he should want.
Ken is surrounded by other Kens. Kens, all of which have the same sole goal: get Barbie's attention.
Like crabs in a bucket the Kens are constantly pulling each other down in an effort to impress her. An all too familiar sight.
Ken exits the Longhouse and discovers his own will-to-power.
Ken is immediately inspired by the achievements of the Faustian man. He develops a fascination with horses, high-intelligence professions, and feeling respected.
Rather than stay in a world where men are obviously better off, Ken decides to return. Like a Prometheus, Ken brings the fire of will-to-power back to the other Kens. Men who he was competing with just days before, men who he was long pitted against in the longhouse.
Ken brings these ideas back to Barbie Land and not only do the Kens love it, but the Barbies love it too. Genuine liberation. A free, complementarian society. Barbie Land was an oppressive matriarchy.
Barbie returns and she discovers the only resistance to Ken is the weird, ugly Barbies and Alan, the androgynous Michael Cera.
I think you already know who these people are in your reality.
Ken's desire for Barbie brought him to the edge, but it was his desire to rise above the mass of Kens that pushed him to take the leap.
When he landed he learned of a world better than his own, and rather than dream it, he shared the knowledge to change his reality forever.
Ken doesn't just exit the longhouse, he returns to burn it down.
