Sowell:"There is a lot to ponder about why both the schools and the housing projects degenerated so much after the bright ideas of the 1960s intelligentsia spread throughout society, leaving social havoc in their wake. Too many people who rose to where they are today because of a foundation of traditional values have become enthralled by the very different ideas prevalent in the elite intellectual circles to which they moved."
Bingo.
Fabian Socialists and the Frankfurt School don't believe in traditional values or the traditional family structure. The damage from these ideas spread throughout the society. Or they undermine places like Notre Dame when their leaders embrace those ideas.
