You keep repeating the earning potential, but there are poor people that get laid and rich people who aren't getting laid.
I mean, we have already agreed that it is about being attractive and that cool people is attractive. I think that we also agree that there are many ways to be cool.
The counterpart is that there are also many ways to be not-cool. Being disrespectful or terrible to others is one. People who is "not-cool" usually have it harder to get laid.
But there is also people who is cool but maybe they are shy or unlucky and don't get laid either. That people might need to hear that they are cool in their own ways and that it might be no ones fault, just bad luck.
