Okay, I'll weigh in, now. My wife is a project manager for a multi-national company. I work in an independent consultant's office. Guess who has the bigger paycheck? Yes, hers is more than double mine. And mine ain't half bad.
Money issues are divisive when there isn't enough money in the household. When both partners are mature enough to work together, then the money doesn't apply pressure one way or another. Too many people, in my experience, don't get to that stage of maturity, especially men. I do not know one other married male whose wife makes over 2x more than he does.
BTW, the hindrance to females should be obvious to everyone. Shame on anyone who doesn't get it. Hiring a female, in many employers' minds, instantly raises the prospect of "maternity-leave". Especially if she's married. That's a year of paid leave just when a young new hire is getting on her feet in the business. It's a fact of life, and these days employers really can't justify avoiding it.
To all the female engineers (female professionals of all stripes, in fact) out there: The real problem is society's inability to raise boys into men with mature attitudes.
To all the males out there: Grow up. If you think being the principal bread-winner is the way it's supposed to be, you don't realize you're missing something even better!
