Ah but she is capitalizing on other's labor, she 100% has employees in at least some fashion, be they housekeepers, pilots, tour bus drivers, shirt makers (probably literal sweat shops contracted out tbh), vinyl pressing plants, CD pressers, printers for the art for those, probably a roady or two to hump equipment of some sort, she is employing some people. Some of those are likely third parties who are in turn exploited by their boss capitalizing on their labor, making her a degree of separation from the exploitation in that case but still she benefits and profits directly off of their exploitation.

No, not through her own productivity. At the start of her career, she had numerous song writers who were arguably exploited in that they are not getting a cut of her earnings. Even now, she doesn't play every instrument on a track. She has a whole team of producers. In concerts, she plays with a band. None of those people are making a fraction of the ludicrous money she's making for "her own product".

But beyond that, like the other commentator said, she has tons of staff of whom are exploited at a paycheck.

And beyond that, all of the merchandise she puts out employs many, many different exploited individuals to make.
