The rest of the article (book?) is about the author's slow growing awareness that non-Americans are warped by these distortions of reality too, in ways that are just as self-delusional and self-destructive. Yes, power does corrupt. Absolutely.
Frankly, I have a hard time seeing how anyone over 30 could find this piece compelling. It's founded in a childish self-centered view of the world, a self-indulgent bubble that finally popped for the author, but not until age 30?
Has this become typical? Even an Ivy League American student can be so insulated that they're not aware that people elsewhere in the world see the world so differently? That their disenfranchisement from power, both locally and globally leaves them bitter and mistrustful of all forms of authority? Who doesn't know this? Jeez. We just elected TRUMP, dammit. Who isn't aware that even the average American feels disempowered by the routine abuse of authority by self-perpetuating elites?
Likewise, I was equally taken aback at the general public's response to "Hillbilly Elegy" as epiphany. Back in the 1970's I lived on the edge of Appalachia, which left me well aware of the subsistence lifestyle in rural America that the book revealed as something new (to most?). Are such wide dynamic ranges of experience in and outside the USA really so invisible to most of us?
If so, that's freaking inexcusable. We live in an era where the ubiquity of the Net can make you aware of virtually every aspect of human experience on Earth in less than a heartbeat. Just open your eyes.
