The issue is objectification.
And you're nitpicking this list to find reasons to exclude these women. Here are some facts, Xena...
Mariah Carey - born and raised in New York, and had a difficult childhood. Raised with her two older sisters by a single mother who was a former opera singer w/o a job, Mariah and her siblings were often forced to move around and stay with friends. "Those were frightening periods," Carey has said of her childhood. "I always felt like the rug could be pulled out from under me at any time."
Celine Dion - Dion was born in Charlemagne, Quebec, Canada, the youngest of 14 children of Thérèse, a homemaker, and Adhémar Dion, a butcher, both of French-Canadian descent. Dion was raised a Roman Catholic in a poverty-stricken home.
Jewel was middle-class and raised by singers so she's privileged? lol, have you read her account of her childhood? Here's some of what she says, without going into detail about how abusive her father was to her mother and she... "She married Yule Kilcher, who was a young idealist who hiked across the Alaskan glaciers by foot, with a ladder on his back, which he used to bridge crevasses in the ice so he could walk over them. He was looking for adventure and new land, away from the Nazi movement. Alaska was still not a state, so he was given (as all takers were) 600 acres of land for free if he promised to homestead it.
I got my love of language from Yule. He studied the origins of languages. Ruth taught all her 8 children (she gave birth to most of them alone in a dirt floored log cabin!) to sing and play instruments. I was raised outdoors on the same homestead my family settled.
We lived far from town. We had to walk 2 miles just to get to the saddle barn I was raised in... No running water, no heat- we had a coal stove and an outhouse and we mainly lived off of what we could kill or can. We picked berries and made jam. We caught fish to freeze and had gardens and cattle to live on. I rode horses every day in the summer beneath the Alaskan midnight sun.
My parents divorced when I was 8...I moved out on my own when I was 15. I had a cabin not far from my dad’s. It had one room and no water, no plumbing, and I worked several jobs. I rode a horse 12 miles into town for work and left my horse at my aunt’s place (who lived close to town) then hitch-hiked the rest of the way in."
I'm not going to defend each woman to you. Suffice to say that these women, each in her own way, exemplify taking on the challenges of life as a woman and making her own way - no objectification for any of them.
That's the point I was making... but I doubt you'll see it as you seem to really want to keep your view of how put down women are by men.
