And yet...it's the woman who does the shopping and manages the household (typically). In planning the food budget a man would be wise to seek his wife's input.
And by the way, Mater stated "everything they both do is for the family, not for themselves". You stated that to determine what is equitable is not the wife's decision. "To determine what is equitable": what does that mean, exactly? That we each get 50% of our labors? I'm confused here. It SOUNDS as if you're saying that the husband has the right to decide, for example, that if his wife cooks a meal, he's the one who decides who gets how much and what. Or are you just speaking of monetary income?
