Frankly, a real man isn't afraid to have his wife make more than him.
My husband and I make VASTLY different salaries. I chose lifestyle over money, and he chose big time corporate. But, that wasn't always the case. Last year, when my husband made the transition to the private sector from public, I was already in private. So, I made about $20K more than he did. What did he say? "Honey, I am fine with you making more money. Hey, can I be a kept man?"
Then when he entered private and now makes 2.5 times what I do...he still wants to be a kept man. ETA:
