I have only this much support for the modeling industry, for it is mostly vanity.
However, it is an interesting look into a model's world view from this article: That they make 1k-5k a show and highly freelance dependent. And many times the cause of Anorexia.
It is not a good fulltime job for the wearers of designs. Which is no wonder many took up a second job. A very common one is being a photographer.
