I assume there's something wrong with the contracts, because it's obvious to anyone following the industry, and it's been widely and thoroughly covered for decades (see links at the bottom or search the press, university publications, or ProQuest). It's true for all these contracts, and especially those with black artists and athletes.
Kanye made specific points that the contracts are unfair, with 'talent' not being paid fairly, and having their creative freedom restricted. He also argues that control over distribution is essential, and black people are underrepresented both as record label owners, and as distributors, therefore leading to a huge power imbalance. All those facts are true without needing to go into the 'Jewish' stuff.
People who focus on that controversy are helping these scum-of-the-earth industries survive for longer than they should. Artists should own their output. They need managers and agents, but those should be employees and contractors, not "owners".
I personally don't care to psychoanalyze Kanye, it's none of my business and none of yours. He has objectively been victimized, and became successful in spite of it. I empathize with him and hope what he points out will be resolved.
