My parents started with very little and were the only ones in their families to graduate from college. As parents they focused on education but did not stop at academics - they made sure that we knew music saw art and theatre and traveled - even though it meant budgeting like crazy.
Of course art world ethics are important. But museums are no purer than any other institution or business. Academics aren't necessarily more high-minded than gallerists.
I also take pleasure in the so-called negative power in Grotjahn's work. That is I love his paintings for what they are not. Unlike much art of the past decade Grotjahn isn't simply working from a prescribed checklist of academically acceptable curator-approved 'isms' and twists.
