It's somewhat disturbing that you would claim I'm "victim blaming" by asking for details on what these "unsuccessful marketing musicians" actually studied. "Victim" is a wholly inappropriate word to describe being unsuccessful at something.

You initially added nothing to the conversation, except for a very brief and vague claim about how you may know some people who contradict my own experiences. So, I'm not sure what kind of response you were hoping for, but a little snark never hurt anyone, and you're overreacting to it.

If you have an actual example of a musician who studied marketing and business but was unsuccessful, I'd love to hear about it, because I've simply never seen it happen.
