I'd wager the problems are more related to self-confidence, the ease in which you can avoid social interactions, and the root issue that you don't get laid as a man until you learn how to approach and talk to women. Some men never even learn how.
The simple economics of sex (men having to pursue women, women being the selectors, just like in the rest of the animal kingdom) explains most of it.
Surely if it was just about confidence in itself, evolution and sexual selection would have made all men super confident by now.
The truth is men are mostly obsolete and worthless by the standard values that have been in place since the discovery of agriculture -- phisical labor is a lot less valuable thanks to mecanization and automation, the police, professional army, social wellfare have taken away a big chunk of what made men valuable before.
Wouldn't this be an argument in GP's favour?
