>>20460851Because believe it or not: becoming a brain surgeon is easier than becoming a commercially successful musician or rapper.
Becoming a brain surgeon involves you to memorize tons of concepts, practice the same procedures for hours on end, inside the comfort of a college. It's part of a medical program, which you pay for or the taxpayers pay for, depending on which country you're from.
Because it is a college program, it has structure, and one has to merely autistically sit through classes, do what your professors tell you, get good grades by passing theoretical and practical exams. Easy
Becoming a (commercially successful) rapper is not a straightforward career. Being "able to rap'" is not a metric for being a rapper. You need to have excellent people skills, you need to be able to network excellently, have great social skills, be really intuitive and intelligent to "read between the lines" when people are talking to you, in order to spot opportunities. And then be driven enough and hardworking enough to jump on those opportunities. On top of that, you need to appear to make music. You must be able to creatively lie, sweet talk, hard talk, etc. You need to have real artistic skills (not to rap, lol) but to create a marketable aura of yourself.
In short, you not just need to be a psychopath Machiavellian, but a top 1% psychopath Machiavellian, in order to be a billionaire rapper/singer/athlete/businessman/lawyer/scientist/engineer/doctor
