Two kinds of men were 5 times more likely to cheat on their wives – those who were completely dependent on their wife’s income and those who earned significantly more than their female partners.  Apparently, you can’t win for losing… or winning!?  So Laid-Off Dude, Stay-at-Home Dad, and Jet Set Darling are more likely to stray, while the opposite is true of women.  Economically dependent women are less likely to cheat.
