I liked the article, so I shared it.
I think what he did, which I haven't read before, is globalize the phenomenon, which I appreciate, because I find the national boundaries we draw around our problems something a distraction.
I'd also add that if you think writers in published magazines aren't self-promoters, you aren't a very careful reader. Most think pieces are an appeal to some group. For me, the most obvious are the right wing "independent" thinkers whose opinions always seem to line up with capital. Ezra Klein recently gave the game away when Israeli's unpopularity forced him to abandon his pro-Israel stance for reasons that have been obvious for since 1948.
But appealing to audiences is part of the game across the political spectrum, it's not something "this generation" inventeed and therefore you do not need to weep for them.
