1. There was a major change in the American economy just under ten years ago, and many “boys” are reasonably postponing marriage until they are better established financially. Similar behaviors have been observed in the past. Many women probably have similar concerns.
2. Due to changes in medical care over the last century, it isn’t such a big deal. When a woman finds out she is pregnant today, she can assume that she will be marrying off her offspring in 20-30 years. In the past, the liklihood of both her and the child being alive in 30 years was not very good. Indeed, the chances that both the mother and child would be alive a year after conception was troubling (many mothers,and most babies, didn’t make it). The bottom line, relevant to our discussion, is that people who delay marriage until their late 20s or early 30s can still end up producing a “house full of children”. There is no reason to panic.
3. If one looks at the cost of raising a child, even paying tuition, and compares it to the life time income of the child, it is clear that having children is a good investment. It would be tragic if people give up having children since they think it would cost too much. There are some cultures and countries (as a country, Japan is a good example, as a sub-culture, secular Jews are an example) in which people prefer to maximize their enjoyment of life by not having children so they have more money to spend on themselves – which in the long term is disasterous since you end up with a community of old people with no next generation and no future.
