This kind of superiority complex is born out of ignorance and the propaganda rooted in "feeling better by putting others down".
No matter who you are, there is someone better looking, smarter and more accomplished than you are, so this kind of "feel good" feeling is just someone projecting their inner shortcoming and insecurity. Not everyone has opportunities to better themselves, and Allah has asked all of us as Muslims to level the playing field. That my brother - is a true Muslim, who helps their fellow human being, not one who puts others down to "feel better" about themselves.
I will not preach too hard because I have this fault too - I do Gibat (Ghibah) constantly. May Allah show me (and others) the right path in avoiding this pitfall. :-(
