one of the Kens asks to be on the Supreme Court, and Barbie says not until a woman in the real world gets that level of power.
I’m afraid your memory is a bit off. A Ken asks for a supreme court seat, President Barbie says “maybe one of the lower circuits”, and shortly thereafter the narrator says something like “maybe one day the Kens will enjoy all the rights that women do in the real world”. The movie certainly did not erase Ruth Bader Ginsburg and Sandra Day O’Connor.
