Why do people from IITs and IIMs think they're superior than anyone??

Like I met some people, they think they're the only smartest people exists in India. Why do you have to be an asshole? Like bro you're even that smart!? Tumhara EQ ke naam pe -10000 hai. IQ toh achha hone se sabko fayda nahi hota.

You're not even living in the real world. 😬😬😬

I'm sorry If I am too generalizing but I feel this so I'm posting it.
