They wouldn't be above average if others had the opportunities they had. They know this.

Edit: one potentially positive takeaway here. I was right wing in my youth. Probably because I was indoctrinated into it. However I was always of the opinion that communism wasn't evil and was just another way of doing things. I eventually realised that capitalism was the great evil of the world and my allegiance shifted more and more left. I hope that the person the replying here is just young and hasn't yet made the great leap yet.
