The bit about Cobain's suicide felt like it was probing around something important but blaming it on Capitalism felt a bit off. Cobain would have experienced something similar at any period in history, that is what happens to talented people who rise from the masses. If anything capitalism gave him way more freedom to use his talent how he wanted than any other system would have.
I am not an expert on Nirvana but I would guess his suicide was more about his personal struggles than some grandiose statement about politics and capitalism.
Afaik he had psychiatric issues that made suicide more likely ... and drug dependence that also made it more likely. He did not even needed to be talented one to rise from the masses, people like him commit suicides more then general population simply out of own suffering. He had bipolar disorder, depression and ADHD.
He also had a severe GI disorder that caused him constant pain, and from what I recall reading, the medical system wasn't able to properly diagnose or treat him (no surprise, our understanding of tricky GI disorders was not terribly advanced in the 90's).
IMO it's likely that some or all of his mental health struggles stemmed from a completely dysfunctional digestive system. In any case, blaming his suicide on capitalism seems like rewriting history to fit one's preferred narrative.
