Male Chauvinist Pigs Make More Money?

That's what this article says on the livescience website:

Men With Traditional Views on Sex Roles Earn More Money

Isn't that interesting? The comments at the bottom gave some interesting ideas as to why there may be a correlation.

I would question whether it's just a simple issue of age of theology, because older individuals tend to have more traditional beliefs and they tend to be further along in their career hence making more money. I wonder what the trend will look like in about 50-60 years.
