Ironically, this article has made me angry about it afresh. Kylie isn't "self-made" for all the reasons mentioned, but also loads of reasons the author conveniently left out. She already had an audience who would have bought literally anything with her name on. She could have become a billionaire overnight selling plastic dog turds.
Whereas Jeff Bezos, Bill Gates et all may have come from money, they also had to come up with a product that met a gap in the market. They had to publicise it. No one bought from Amazon when it first opened up up because they were already a fan of Jeff Bezos. So completely different.
And the idea that Kylie has anything to do with her products, from conception to formulation to sale is laughable. All she does is put her name on it.
