Sure, I'm saying in many cases the math doesn't make sense. It has been this way for most of my adult life. I have known couples where when you subtract the cost of child care from the lower of the two incomes the difference was minimal. But the message is both parents have to work. I'm just saying many people never do the math. If they did they would not say that. Not making a moral judgement here, other than laziness and dishonesty with ones self.
