I think Cameron might understand her situation better than outsiders do, I'll give her the benefit of the doubt that at least that she knows what's she's doing. And in things like photo shoots she sure is an object. It's not about what a smart girl she is, how great a GF she's make, how awesome she is as a mom - it's about her body as canvas and that's pretty much it (and at that, it's a pretty small window where she gets to do that). In much the same way that I heard a designer once refer to the runway models as 'moving hangers.' It's not about them, it's about the clothes, and the ones that are successful do not get there by wearing the clothes as much as they have the ability to let the clothes wear them. If you - as the audience - are focused on the model and not the clothes, then they just did the job wrong. It's not saying anything else about them, their personality, their other interests, the rest of their lives, it's about doing a job - that specific job - that's all. BTW, that's why so much of the fuss over "plus size" models gets coverage in the press, but not on the job - to the degree that you're focused on what size she is (and not what the clothes are like), then the point is being missed. The job is to sell the clothes, not to sell the model. She's just a moving hanger. Just like Ms. Diaz is pretty much a canvas to be painted, covered and shot.
And at points we're all objects. Everything in life does not take into account the totality of our existence, but might just be one thing about you - and that's it. In the way that one of my crew people on a tour once told me that I treated them like they were gear - and I had to remind them that, in fact, I treated the gear much better as the gear was the show, and they were not. I'm sure they were wonderful people with a myriad of skills - but all I needed was a warm body with a strong back to move crap from point A to point B and back again later. The rest of didn't matter - nor should it have. And when anything outside of a warm body with a strong back became an issue, then it was to the detriment of the job, not to it's enhancement. (Which is why I (and just about every other boss type in the world, does not really want to hear about anyone's problems/issues/personal life at work - at least when were working)
In fact, a vast number of the people you'll interact with - well you do it as objects, and vice-versa. They are staff, you are customer, teacher/student, crew/rock star, doctor/patient.
