Through academification, Jazz is treated like a 2000-year old rigid mathematical framework that you need to practice correctly for 15 years before you're allowed to speak on it. The priests training to do this need $5000-$20,000 for their instrument(s), a private tutor for a decade, band camp every summer for 4-6 years, experience in 3-5 ensembles, and then a bachelor's degree in music at minimum, so about $30k or so just for the music classes part. Then and only then can you truly appreciate the theory of "Charlie Parker improvised using registers" and, "Jazz is about knowing when to play the wrong note, honky".
