I've never understood this ridiculous argument that is a favorite of this forum, modelling agencies are not charities nor is the modelling industry a meritocracy. Favouritism has always been a part of modelling, a model's success is not determined by how much she works but by the model's look arousing some kind of interest from fashion editors, photographers or casting directors. If Brokaw or Meisel see something in you, it doesn't matter if you've got any experience, you can now waltz your way across top-jobs. Most models can work all they want but they will never access modelling Olympus.
All in all that argument just sounds like a very lousy version of the old "poor kids in Africa" to manipulate people based on guilt. The reality is that the majority of those girls were going back to their "lifes of poverty" regardless of Instagirls, simply because they've chosen a career where luck plays the key role. Kendall, Gigi an co. are not stealing away any jobs.
