That is if you define "The Arts" as specifically "Archaic forms of art too unpopular to survive without subsidies from government or the aristocracy". That's a tautology.
Hip hop music isn't getting government subsidies. DeviantArt isn't getting government subsidies. Etsy isn't getting government subsidies. Youtubers aren't getting government subsidies. The Marvel Cinematic Universe isn't getting (many) government subsidies.
>>The Marvel Cinematic Universe isn't getting (many) government subsidies.
Maybe not US subsidies, but I'd bet that there are some Canadian film and tax credit logos at the end of most credit reels. When you film/edit/design/create on an international scale, you pick up lots of local tax credits. Also probably UK/Scotland credits too. Heck, the 2005 reboot of DrWho was backed by Canadian government money. (Just check the final credits.)
Those are usually granted by local governments to increase local revenue, not lower it. It's how one jurisdiction can attract more investment relative to another.
The article under discussion, though, isn't about arts that are surviving as for profit businesses--which includes all of the ones you mention. IT's about arts that aren't doing that. Those are the forms of art that the GP comment was about.
