On a basic level the message “Ken was silly, broke Barbieworld because he wanted to emulate men, they had to get Barbie and a feminist back to fix it”
How did he break it? He basically just flipped the genders so Kens are the ruling/working class and Barbies are just subservient eye candy. Barbie just flipped it back. It’s a broken and unimaginably unfair world in either case.
When Kens ask just for a bit of equality at the end, they are shut down and given some unimportant appeasement as a joke.
Can’t help but be reminded of something.
