I tend to agree that costs aren't the only factor. Poor people have always had kids, usually more than wealthier more secure families. I think the bigger question is why security is increasingly becoming an pre-requisite. I think it may have more to do with increasing cultural expectations we put on mothers and parents. There was a times were it seemed like these expectations were much lower than today. To hear it from friends born in the 40's to 60's, the typical duties of parents basically ended at providing a roof and two meals a day.
