I agree with a lot of this article, but the answer here is definitely not to enable more people to go into the arts on the public dime. If you want free college, let's have it be free for everything except the arts. If you want to get an MBA, or learn mechanical engineering, i'm happy to subsidize that. But I have no interest whatsoever in subsidizing your creative writing degree.
I really enjoy going to the theater and seeing performances of all kind, just as I like tech/business advances. I want people to enhance the arts as well as the sciences.
I acknowledge the idea of focusing on marketability and "ROI" for someone choosing their own path... However, when providing "access" to education, why encourage someone who could write the next show I want to see to instead consider crunching hard maths that they don't care about?
