That's a whole new debate Fubaar, and one which has been covered in the media recently.
Humans are not rational (as much as we like to think they are). They tend to take the path of least resistance even if it's a completely stupid one. They also tend to like grand-standing. Parents dress their 5 year olds in teeny tiny skirts and 3 layers of makeup, and train them how to look, walk, and speak, so they can win beauty pageants. They argue violently over kindergarten/primary school soccer "matches" where the kids barely have the faintest idea what they're doing, but just like kicking a ball.
I don't pretend to know why this happens, but it's a fact of life these days.
