Why don't men have as many low self-esteem issues as women?

Females seem to have much more low self-esteem than men. I know a lot of it is because of the media, but it seems like men don’t seem to be as affected by the media. They don’t feel pressure to look good, muscular, etc. It seems they aren’t that threatened by men with good-looks.

Even when it comes to skills, status, etc. guys seem to praise each other and envy them rather than be jealous. Why are most women programmed to feel threatened?
