Given our lopsided wealth distribution, why don't we redistribute and make our musicians more well to do? Another tax is really a great idea, it wouldn't solve everything but would help make a more equal society if it could be applied without corporations avoiding it. We already have enough production and even unemployment! We have more than enough spare labor capacity to let people try their hand at music more freely. In any case, I know several musicians and they essentially get repeatedly spit on by society, work for peanuts, and never give up on their mission even after sometimes becoming near suicidal. The current system is inhumane and starves us of non-commercial art.
