Firstly, no, I live in Europe, not the US. And secondly, quite a few of my friends are working models or work "in the field". I do some work every now and then but wouldn't say I "work in the field". The fact is most models don't make a great deal of money, a few do. There just aren't that many big ad campaigns available and that's the only thing that pays a lot of money. Runway shows, even for bigger brand ones like Armani, don't pay much more than €1k and agencies in Paris usually take 50%.
Mind you, some of the models I know make a lot of money but most of them only make a decent living that's not much more than someone working a regular desk job.
All of that is beside the point, though. TR photographs a LOT of models. If you look at his tumblr page he basically has new nude shots of new models (male and female) almost every day. He surely has photographed thousands of models throughout the past 15 years. Do you think all of them have so much at stake that they can't speak out against him? That's just not the case. And plenty of them actually are not afraid to say that he's a creep (while others love him). I just had drinks yesterday with a model who told me what a creep she found him to be in their few encounters.
