Surprising how often CFTC Rule 40.11 is misinterpreted.
The Rule allows CFTC to prohibit contracts in specific categories only if contrary to the public interest.
Not an outright prohibition of all contracts in those categories. By rule, default is to allow, not prohibit.

Terrorism
Assassination
War
Unlawful activity
Gaming
Key word: "Gaming."

Not surprising at all.
Elite universities are inherently exclusionary. Inclusivity is a brand killer.
The brand is built on who gets excluded, not on who is included.
SAT is crucial for excluding bad candidates.
