I think you may be misreading why the lack of philosophy education matters here. The point is that billionaires and CEOs now present themselves as intellectuals or thought leaders, without having done the homework, and end up using and abusing philosophy as a guise or shield. They end up creating short- and long-term negative effects that could have been easily avoided as all of these philosophies have been heavily litigated in even undergraduate level philosophy courses.

It's not that these individuals are not smart or capable, it's that they lack the dedication or care required to do these ideas justice. It's easy to see how someone can read Girard and obsess over the antichrist in the twilight of old age. However, a more rigorous engagement with philosophical foundations would offer them the breadth and perspective to be free of that narrow obsession.

It's about diagnosing why billionaire/CEO intellectual hubris makes them incredibly dangerous and sloppy thinkers.
