You didn't say they were the creations of capitalism, true. I'm just disagreeing with the idea that capitalism led to major benefits for the BLACK creators of those genres. Did capitalism help...Howlin Wolf get more shows in the 60s and 70s? Sure. But capitalism also ensured the blues (and rock) were effectively pillaged by white artists who earned far more money off it than the black creators. Not to mention the (white) record label culture vultures who swooped in and bought the rights to a lot of that music.
In terms of these things only being capable in a capitalist society...gonna need evidence of that. Because all those genres were created under the worst possible environment for people (slavery and jim crow). If you can create and enjoy art while slaves, I'm pretty sure you could do the same under a socialist regime. 
Def cuts both ways. Like I said, I don’t think capitalism is perfect. No system is.
I’m conflicted on the claim that all white bands then cribbed from black musicians. Or at least, deliberately stole.
Back in the early rock days they would often play music they just loved. And would almost always, and I could be wrong on this, give credit for where they got that inspiration. There’s exceptions to this of course and certainly your case of racist rockstars (especially of the blues bent) like Clapton.
But I think it’s far too cynical to say that they all deliberately stole from black musicians.
I think Jimi Hendrix throws a wrench into the argument. When jimi first started playing with these bands he recorded and played covers. They all played shit they adored and placed in high esteem. The first night Jimi played with Cream he played Wolf’s Killing Floor. His first major hit was a cover called Hey Joe. All along the Watchtower. These guys liked paying tribute to artists they idolized and often would be open to where they got it from. Even to the point of inviting blues kings to the U.K. to tour to give them viable business. So if they loved Muddy Waters they’d give Muddy a bone and be like,”I got everything I know from Muddy” and have him play.
Even when they didn’t give credit, as Led Zep did with You Shook Me, the song is so dramatically different from the original that the accusation of stealing almost sounds like a stretch.
Did some white musicians steal from black musicians? Certainly. But I think this takes away from artistic process and inspiration. Or else you could say hip hop producers stole from the people they sampled from. Clearly in both cases the musicians were just inspired by the music they heard in their youth.
This is now a music thread.
When did YOU get into the blues? What happened to Mr. “I don’t get jazz?”
I could talk about this shit all day breh.
What is your favorite blues song?
Sorry for the late reply PD. I’m at work as my partner today is being slow af. I have my numbers down because of him and have to work much harder now. Smh.
