Not the other guy but IMO it’s pretty simple. Academia is for the pursuit of knowledge, you learn and the you contribute. That may coincide with making money and running a business but it does not have to. If you want to make money and run a business that’s what vocational studies should be, you learn a trade for the purpose of “being successful in the outside world”. The issue with society today is that we’ve come to glorify higher education and view vocations as some kind of negative. Academia in a modern society should stay focused on the pursuit of knowledge not on the pursuit of churning out degrees to make certain jobs look more legitimate than other jobs. Pursuit of money and running a business should be territory of vocational schools.
There is no pursuit of knowledge in becoming a Youtuber or a Twitch streamer, so it should be taught as a vocation and not as a part of academia.
