Great stuff, especially the first one, “America’s Ruling Class”. If you’d like some belly laughs at the expense of political elites, I’d recommend “Radical Chic” by Tom Wolfe (1970, only 90 pages).
The subtitle was Mau-Mauing the Flak Catchers, I remember. Read some excerpts, it was very clever and an instant classic. I just didn't feel like reading about black nationalists ripping and raging at white people, while guests at tony Manhattan parties hosted by Leonard Bernstein.
