Not just women. Men have little chance at advancement. So I have seen many cases where they stay home. The women has a chance to get promotions. But her husband is wasting his time at work. He will never get the promotion he is qualified for. So he just stays home and she works. I know of several of these situations.
I know of a couple in auto industry some years ago. The wife was the main breadwinner. The husband quit to be a stay at home dad, but still did consulting work. The wife was putting in long hours so somebody had to be around to be a parent.
