MBA and Dosa - The Idea of Bullshitting

Why has MBA become such a thing? This is a line of questioning along the same lines of 'Why does a dosa have to be circular in shape?''

Even though I don't have an answer, since I am a wannabe influencer, I am looking to come up with random philosophies and create a nonsensical vibe for myself so that I can become an "influencer", whatever that means.
