Look I'm just keeping it real.
I'm not arguing who contributes more to society, although have you never heard of 'music therapy'?
Many ordinary musicians are pretty straight. My partner is a nurse and there is a long history of drug abuse in the medical profession. It's a known and quite often reported phenomenon.
Not to mention nurses and doctors can party hard just as well as musicians sometimes do.

In the end, if you can't claim some in society contribute more than others without introducing some wildly inaccurate uber negative stereotype, you probably don't have a very strong claim to begin with.
