You are blaming society (the white majority, that is) for the fact that black musicians were paid less than white musicians. In a market economy, financial benefits are governed by supply and demand. Indeed, black musicians, by and large, did not make as much money as white musicians, but the difference was less than a factor of two. In fact, the majority of white musicians did not really make a lot of money. Of course, the highly successful band leaders -Goodman, Shaw, the Dorseys, etc. raked it in. I guess Benny Goodman made more money than Count Basie. Do you happen to know how much more? I do not. It would be interesting to find out.
What I see in your posts is a great anger at what you perceive as a grave social injustice, the differential in salaries between white and black musicians, although their talents were not that different. I think what you are saying is that the differential in salaries amounts to collective stealing on the part of the white musicians and/or white society. I maintain that stealing, in its traditional meaning, is not a collective, societal action, but an individual one. One individual (or a group of individuals working together) targets the property of another individual in order to appropriate it. There is intention to take, it is an immoral action, it is a very well defined action.
Stealing in the sense you use it is very vague. First, as someone said in a post, how can you steal a style of playing music? You also seem to place a lot of importance in the question of giving credit to the creator. But is there a creator of swing? Jazz as played in he 1920s began to change in the 1930s and became known as swing. As I said before, swing was in the air, so to speak. Who were the musicians mainly responsible for the changes? Only black? Only white? Both? If mostly black, what were their names? And what were the names of the white musicians who appropriated the style and made a lot of money, e.g., stole from the blacks? Because stealing is an act against an individual, in your analysis, white men taking from black men.
If you insist with your notion of collective stealing, it seems to me you must provide some facts. Who were the thieves and who were the victims? Approximately, what was the extent of financial loss on the part of victims and financial gain on the part of the thieves?
