Going down this road the inevitable conclusion is that the wife is a pro too since it is you paying the mortgage and insurance .
So either she is too dumb to get a job and you are forced to support her, your choice for marrying someone like that.
Or you marry her and tell her to quit her job because you want her to be June Cleaver.
Again, your choice so you can't bitch about it.
I really think the guys who bitch about "you pay for it anyway" when talking about having sex with their wives are just guys who made poor decisions on who they married.
