the point made by Chris Hogan is that attending a prestigious college is not a prerequisite to building wealth.
If 99 of 100 people who did C accomplished Y, and 1 of 1,000,000 people who didn't do C accomplished Y, then you can "prove" that C isn't a pre-requisite for Y.
However, 99% vs. .0001% is quite an advantage.
Did anyone ever claim it was a "pre-requisite"?
SET has published numerous studies on gifted individuals and gifted education and the correlation to career accomplishments (advance degrees, patents, CEO-level professions, and, iirc, earnings) and there is certain a position correlation. Is it 1.0? Of course not.
