No wonder universities have no money if they spend their funding elevating self-help books to the status of science courses. Also the OP link has a ref parameter.

That may apply to many universities in the US, but not to Yale. They have the 2nd largest endowment ( $30 billion ).

In Yale's case, they probably have too much money. Enough to waste money on nonsense and not care.

Another theory: The course might be relevant, timely, and thoughtful.
