I'm afraid I certainly have to disagree with you, with my experience differing markedly from yours.
Never underestimate who is helping you get from A to B. My usual routine is to get into a car and find out everything I can about who is (say) driving. I have had a Qantas Captain, various other pilots,  C Suite Execs, business people, and many very well-educated, switched-on people from diverse backgrounds, all with a story and a point of view, often appreciable. I have been so impressed with some of them that I have assisted them with other opportunities and engaged them.
So there you go; most people can be interesting and definitely employable. However, one must want to seek that out!
