I was referring to the marching band. Which as you know, costs a lot more than just teaching music in the classroom.
Also, if you delete the football team, the impact of the marching band is somewhat dissipated.
Additionally, it's a teacher's mindset you possess, but you're too focused on your own discipline. By your standard, ANYTHING done in a school which results in employment in that field at a later date is suddenly "vocational."
I'm sure there are cheerleading instructors and coaches who are employed. So now cheerleading isn't extra-curricular. I'm sure there are people who would like to go into the priesthood. So now the Bible Club isn't extra-curricular. I'm sure there are people who are employed in the stamp collection industry. So now the Stamp Club isn't extra-curricular.
My point, which as a former teacher you were unable to hone in on, is that there are dozens of more extra-curricular things going on at the average school which could be cut before the radio station would ever be sold. It is an ASSET. I know they don't teach that in music, but as an ASSET, it has a value beyond the cost of operating it.
The same cannot be said of the marching band and its equipment which are an outlay of costs with no tangible assets to the school other than selling equipment at a loss.
