I'm sure some of these folks are more happy, adding more value and giving more back to society than you. So no, they are not below you. You should seek some counseling on your poor self-esteem issues.
I've gone back to my last high school reunions and had a great time catching up with old friends and people I didn't really talk to in high school. The smart folks became doctors, lawyers, CEO's or entrepreneurs. Other's are making great money and happy as plumbers, electricians and police officers.
A former basketball/baseball teammate was a recruiter for a company that I was interested in. I sent him my resume, got an interview the next week and job offer the following week.
High School was a great time, maybe b/c I was a jock that loved playing sports and friends with almost everyone. It was great to hear how the parent's of some of my hs friends were doing b/c they treated me so well back then. With it being a small world, later on I would learn that the mother of a classmate was the person who had knitted a scarf for me for last year's Boston Marathon.
