what are modern little girls dreams now?

Believe it or not, little girls nowadays play with skincare products marketed to grown women. The beauty influencers on YouTubeTikTokInstagram have made 7 year olds believe they need serums and lotions that cost $50 (or more) a piece. A friend of mine told me her granddaughter (age 7) asked for skin care products for Christmas.

This is just one article on the topic that I have come across -- https://www.today.com/parents/family/tweens-are-obsessed-skincare-experts-anaylze-trend-rcna127971

I think they play "Social Media Billionaire" now.

To be Taylor Swift or social influencers

My gen Z daughters played with a vast variety of toys, dolls, pets, Hot Wheels (my oldest still collects them), stuffed animals, refrigerator boxes, caught grasshoppers, went on nature hikes, bicycles, skateboards, etc., etc., etc.

They both went through the girlie thing with lots of makeup, etc. Now my oldest is married and very much into cars and drifting. I got her a hard to find oil pan for a project car of hers a couple of years ago for Christmas and she was over the moon! This year her husband an I got her some really great tools and a rolling box that she can take to the track and she was again, over the moon. She still loves to get dressed up and go out and she also loves being knee deep in grease in the garage.

My youngest is still finding herself. She also loves cars and wants to get into drifting. She's pretty fearless and a decent driver, but I don't know if she has the mechanical aptitude for the off track part. We'll see.

P.S. Nothing cooler for a dad than having a daughter be thrilled to get an oil pan for Christmas!

My eldest Niece is in Law School. She's smart, not indoctrinated by social media gossip, and funny.
My next eldest niece is about to go into high school. She's into social justice, but still Big on soccer and karate.
My next eldest niece is going into middle school. She loves arts crafts and cooking.
My next eldest niece is all about unicorns, pottery, and playing with any kid she sees.

The rest of the girls are about to begin school. I'm proud of them and their eccentricities. Any indoctrination comes from their parents. As these kids grow up into adults, they become their own person and accept, reject, or alter what they know.

Have you even read one fairytale? "Falling in love with the handsome prince" is a drop in the ocean, usually at the end, if it even features, just to wrap things up. Hansel and Gretel didn't get rescued by a prince, Gretel was the hero of the story. Cinderella was all about getting out of the house and going to a party, the prince was a bonus. In Rumpelstiltskin, there was a king instead of a prince and he was a tyrant. The Little Mermaid never married a prince, he thought of her as a kid sister, so she became one of the spirits of the air. And on and on.

Not to mention a lot of little girls who start with dolls ending up playing with Barbies or similar dolls, who have different careers and different features. And not all girls play with dolls.

So, your whole question is predicated on a false perception of girls. Correct that perception and you'll find your answer.
