You sound like you have an inferiority complex, you probably were not blessed with a comparable IQ to the people you describe and resent them for it because in SV that's your most important asset.
I'm not that smart compared to the other people you replied to but smart is relative. I chose to go to the 3rd best high school in my mediocre Romanian town and had the highest entry grade in the entire high school. When it came to math I would grok the concepts by simply reading on my own 30 minutes before class while my peers would need tutors and still not get it.
Do you think I had a good time in high school? What my peers lacked in math skill they gained in ego preservation. They saw intelligence as a threat that must be neutralized. I doubt my story is that different. I'm telling you this because it's pretty obvious you did not live it so you might gain some empathy and let go of your resentment
