Militant petit bourgeois

Thirty years ago, Leo Lowenthal, last member of the original Frankfurt School, remarked to me concerning some colleagues
that they were: militantly petit-bourgeois. They sought to be respectable. They were submissive in practice although they wrote
about critical thinkers. They dressed like provincial professors and their houses were furnished in the same manner. They were
polite in person. They circulated gossip. They climbed the proverbial ladder. They served.

In light of Franco Moretti's book, "The Bourgeois," we have been wondering what figures follow the bourgeois.
Here is one of them. There are others.
