Forbes compiled a list of the 50 most valuable college degrees.

50 degrees with the highest pay

In terms of FBS conferences that tends to correlate with the wealthiest schools, and thus the wealthiest conferences, who have the wealthiest alums, give or take. Some are listed for just a single element while others are their degrees in general because a lack of information. However, as a rough guide this is pretty interesting.

Here are the results by P5 conference who made an appearance on the list at least once...

Pac-12:
Stanford

SEC:
Texas A&M
Alabama
Vanderbilt

Big12:
None

Big10:
Illinois
Michigan
Purdue
Michigan State
Ohio State
Penn State

ACC:
Georgia Tech
Virginia
Pitt
Syracuse
Clemson

Notre Dame

Overall, it is pretty interesting. I doubt it surprised anybody to see the Big10, the wealthiest conference, also has some of the wealthiest alums.

Interesting list (although it notes that it's incomplete since many schools, such as Harvard, don't report the salary data).

If anything, it shows that an engineering degree from a flagship/flagship-type school has a very high ROI (with business programs from top schools mixed in).
