Also, having a Master's in music theory is not going to guarantee you a $100K a year job as a corporate music theorist. In case you missed it, the bullet point there is if you soak off your parents going to school for 6-7 or more years to get some bullsh** degree, well then you may want to go ahead and identify that little picture of the cheeseburger on the cash register.
Don't get me wrong. If you are in a stage in life where you are financially independent, and you want to go to college to study Renaissance Macedonian Basket-weaving to broaden your horizons, go for it. College is (or was, in theory, in olden tymes) a place for higher learning. No, not that kind of higher, Smokey McPott. I mean expanding your culture and wisdom. BUT, if you feel that same degree gives you some sense of entitlement to a corner office in a corporate high-rise somewhere, eh... not exactly. Just my opinion.
