This is a fixed-pie fallacy. Someone of mediocre intelligence is not harmed by being in a society of people much smarter than him. On the contrary - he benefits greatly because smarter societies are safer, fairer, and take care of citizens (including the dumb ones). This is revealed by real-life preferences: People from low IQ countries consistently try very hard to migrate to societies of smarter people. People from low IQ regions try to get into neighborhoods and schools of higher IQ people. It's like complaining that Einstein existed because my grandpa didn't get to invent relativity. Well, my grandpa was never going to invent relativity. The fact that Einstein existed just means that the rest of us now get to enjoy the positive externalities created by his ability. It's true that if everyone else is smarter, your relative social status would be lower. But this isn't an argument that scales up, since relative social status is in fixed total supply anyway.
