They mean:
… 1 – Virtue Signaling class vs Virtue Demonstrating class
… 2 – Talking class vs Productive Class
… 3 – Others Pay For It class vs Pay Your Own Way class.
… 4 – Cosmopolitan Class (territorial communism) vs Nationalist Class (territorial nationalism)
Technically speaking, the “Cathedral Complex” consisting of the alliance of the talking class and the underclass:
“Those who profit without warranty.”
… 1 – The Academy,
… 2 – The State,
… 3 – The Media (News, Info-tainment, Entertainment, Advertising, Marketing),
… 4 – The Financial Sector.
We use the term ‘Cathedral Complex’ to refer to the replacement of the aristocratic, rule of law, commercial, military and industrial complex (The people who do) with the propaganda complex (the people who talk.)
When the church failed to reform, the academy replaced the church. It’s not complicated. We don’t have a separation of church and state any longer. We have a state-sponsored church of democratic socialist secular humanism spread by Marxist pseudoscience and postmodern pseudorationalism, and outright denial of science.
