Men Cheat More on Well-Paid Women?

New research suggests that women who make more money than their husbands are more likely to be cheated on… revealing a glass ceiling of a completely different sort. On the other hand, women who depend on their husbands for money are also liable to be cheated on. The Telegraph reports:

What’s a girl to do? According to new research, men are more likely to be unfaithful if their wives are high-fliers – so maybe your marriage will be safer if you stay at home and bring up the children.

Except, unfortunately, that sounds like even less fun: although women who are financially dependent on their husbands are not likely to cheat, their highly paid spouses still tend to stray.

“At one end of the spectrum, making less money than a female partner may threaten men’s gender identity by calling into question the traditional notion of men as breadwinners,” reckons Christin Munsch, author of The Effect of Relative Income Disparity on Infidelity for Men and Women. “At the other end of the spectrum, men who make a lot more money than their partners may be in jobs that offer more opportunities for cheating, like long working hours, [and] travel.”

What do you think – is this evidence of a completely new, unaddressed form of sexism? Should men feel threatened by their partners making more than them? Why or why not?
