So what exactly makes one 'deserving' of modeling clothes and walking down a runway?
Nepotism runs rampant through all industries. Kendall is far from the first or the last to benefit from nepotism. The Hadid sisters didn't exactly claw their way up the ladder and I never see as much criticism for them.
IMO, it's not how you get an opportunity but what you do with the opportunity that matters, and she seems to be trying to make the most of it. She's working, and has a 'real' job, something people criticize the rest of the Kardashians for not having. Yes she's boring, but damn near all the models who walk in shows are boring. Most of the runway models theses days are plain bagels, she just kinda blends in to me. I honestly think the only reason some are so critical of her is purely because of her Kardashian affiliation.
