The exploiter could have made a lot more money, if he had taken better care of the "exploitee" Even a parasite knows that he must not do anything to harm the host; he must keep the host alive. In this case the exploiter wasn't too bright.
Super talented people don't fall out of trees, and there were people at Blue Note who could have, and would have been more productive if the "parasite" who didn't play one instrument had realized that the host must be kept alive.
It's better to ignore this post, than respond to it; does anyone remember "Before the beat, or after the beat"
