Kanye West has been THE celebrity since before the iPhone released, you cannot express the absolute domination over pop culture he had from 2007-2015 if you weren't there, he isn't some online eceleb. If anything, his spiral into unmedicated insanity for the past decade has been because when you are THAT rich and famous, you can never have anyone that you know sincerely wants the best for you and isn't just a yesman and leech after the bag. Even his shitty latest albums are about this.
That's why he made such a big deal about losing billions to catastrophically break all his industry contacts, and how he still went to the top of the charts as an independent without a label. His breakdowns and Nazi posting are about alienating as many people as possible, because in some perverse way it would make him "free".
