The problem with jazz is that it has academicized and the pop music industry and capitalism in general are in a race to the bottom to make the cheapest product for maximum profit. That makes a really bad situation for jazz music, the only people who "really" experience it are rich white (the colloquial version, dont have to be white) people, black people who are in church music scenes or black people who are legacy jazz musicians.

The whining and fighting over the stupid word is missing the forest for the trees, which is "Why did the music become so academicized, so liberal and so white?" It's not because white people called the music Jazz, honestly early Jazz history is kind of dark. No one really knows for sure where the word came from because no one was documenting it like we do everything now.

I think the other issue is that Jazz is a very precarious world and being openly anti-capitalist can put you in a situation where you're no longer play in the institution or the establishments that leech off the community and music.
