Rampage is on a rampage (the most expensive schools are art schools)

After a mere week or so at work, it can no longer be said that Catherine Rampell is the most underrated force in economics writing and journalism (or can it?).  Here is her post on which are the most expensive schools.  It is art and music schools, when you take all relevant costs and financial aid into account.  Excerpt:

Now here’s a list of the top 10 most expensive four-year private nonprofits, after subtracting the average amount of government and institutional grant/scholarship aid at each institution:

1. School of the Art Institute of Chicago

2. Ringling College of Art and Design

3. The Boston Conservatory

4. Berklee College of Music

5. California Institute of the Arts

Do see the earlier MR post “Artists grew up in households w/typically higher incomes than doctors did.”  What does this imply about the competitiveness of the sector?  About our models of child-rearing?
