The network value of knowing a rich person far exceeds the network value of knowing a smart person.

This is why https://www.economist.com/graphic-detail/2015/10/29/our-firs... concluded that the best university in the USA is https://en.wikipedia.org/wiki/Washington_and_Lee_University.

For this they measured the gap between what graduates made, and what they would be expected to make based on high school record, test scores, and choice of major. In other words, "How much do you earn because of the university you went to, rather than your own virtues?"

That university won because it has a network rich people who could help people's careers get a good launch.

If you're measuring the value in dollars, it would be very surprising if people maxxed on the INT stat rank higher than those on the USD stat. But, for example, if your goal is to secure a professorship at a top university, or do the most cutting-edge research at a national lab, I think the network value of knowing a smart person far exceeds that of a rich person.

Kind of depends. Attending a service academy in the states is a VERY GOOD IDEA if you want to make being a military officer your career. But yes, I take your point for the general case.

However... some of the best business contacts I have came from teaching at a trade school in Texas. But I'm just selling solutions into SMEs, I'm not baby-sitting kids with VC funds.

How are we valuing the network? There are doors that many wealthy people would not be able to open and vice-versa. On the other hand, someone both smart and wealthy... Sam Altman comes to mind, as well as a number of other figures of historic importance.
