Something they completely ignored in Barbieland
Okay, correct me if I'm wrong, but each Barbie (and even the Kens) represent real-world dolls that are owned by people worldwide. These living people in this fantasy world are affected by anything that happens to their doll counterpart in the real world, including if someone is currently playing with them, or even physically holding the doll in question.
What's interesting is, they never address what happens to truly abused dolls. It's one thing to have Weird Barbie there, that she has messy hair, and crappy outfit, and permanently stuck in the splits. But what happens to the Barbie's whose real-world doll suffered some truly cruel fates?
As someone who grew up with Barbies myself, I saw things happen to other people's dolls that is horrifying to a child (and makes an adult feel sad or possibly experience horror too). I mean, a common thing little boys (who were being mean and their parents didn't stop them) would do when I was growing up was to strip the dolls naked, pull their heads off, and then run off to play with something else. Thankfully, my brother was far more respectful of my dolls, and if he had attempted it, my parents would have spanked his ass.
But in other homes (and even daycares) I saw barbies neglected, chewed up by pets, thrown in the garbage, dropped in pools and never dried properly, barbies drooled on by babies, etc. I've heard about barbie dolls ending up in the dump, thrown in sewers, burned on grills, their bodies torn limb from limb and the head used for some weird sculpture, I mean, a lot of dolls out there meet a horrible fate, one way or another. The least-bad fate is being stuck in storage for generations, or kept on display in a collection, or handed down from one generation to the next and the owners are taught to be kind to their dolls and handle them carefully. (I actually had the privilege of playing with my aunts' 1960s vintage Barbies when I would visit grandma as a kid :D ).
So you gotta ask yourself; what happens to the living women in Barbieland whose dolls suffered the horrible fates mentioned up above?
