Just as an additional data point to the conversation, I didn’t know who the author was (I don’t live in the States) and I think this was my first time visiting the website on which the article was published, and as such I thought the author was more on the left of the political spectrum.
I didn't know who he was either, and regardless it's possible for him to be both alt-right and on the mark in this article (although I assume that I had a similar response to you, I was a little disconcerted to see him described as alt-right).
In my limited experience huge swathes of the so-called alt right are, regardless of their other political positions, just as dismal about their economic future as the young left, and they have no illusions about concentration of capital, etc, since the 80s and have drawn similar conclusions.
