If a woman home schools the children I think her services are very valuable. But if she does not home school and sends the children to public school I don't think her services are that valuable. Most of the work in keeping a home has been made far easier than it used to be because of modern technology. How much do day care workers make anyway? Very little, and they take care of many children at a time, not just one or two.
This is completely unfair... some husbands refuse to homeschool their children, or even allow money to be spent on it. That’s not the woman’s fault in fact she’s being obedient to her husband by respecting what he wants for the children/money. Wives do a lot more during the day then I think you realize. Txtrad listed some very good examples.
