Humor, Modesty and Compassion!
I am a member of Mensa and read ca. 2000 books in the last 30 years. Sometimes I think just like you, although I know it is wrong (and I would never talk about it).
I often meet people who say things like "I find that anyone who isn't a PhD ... might as well be a paper shell." are too shallow and stupid for my taste, and I am one of them. Overconfident, not nearly as clever as they think they are, boring idiots, arrogant. They just think they know, but actually don't know shit about quantum mechanics, general relativity, cohomology, lisp or russian novels and Debussy.
Conclusion: Thinking that other people are stupid, shallow and boring is only allowed if you are a genius - and you aren't. Nobody is. A good life has kids, sports, wine, sex and vodka in it :-)
I prescribe 25 short stories by Chekov and falling in love immediately.
