The article and some of the comments here seem to suggest that there's something more "authentic" about a piece when it comes from a subversive, low-power position. Why? What makes the perspective of someone in a position without power more authentic than the perspective of someone with it, other than the fact that it will probably resonate more with the personal experiences of many more people since power tends to be a pyramid with a much wider base than top?
The real answer is to carefully consider where the perspective of whomever is speaking is coming from, and identify how closely it aligns with where you are and want to go. The perspective of a billionaire on how hard it is to make ends meet, if you're living at the poverty threshold? Probably not that relevant. The perspective of a billionaire who started out poor on how he got to where he is? Probably pretty relevant.
