> Devils Advocate: The desire for kids is wired into us at a very low level. It's not quite a basic survival need but, but it's near that level psychologically.

There are other things like solving problems by violence that are similarly wired. This does not mean that in the modern society this is acceptable. In the same way having children should be considered as an expensive life choice.

How is it not a basic survival need? Most societies don't have social security, pension funds etc. So, kids are the only way to survive beyond the state of being young & healthy.

But this does not hold in the first world. So in the first world it is a (IMHO rather expensive) life choice.
