I think it is a mistake to count savings on raising children as a benefit of life extension because there is no intrinsic link between these two things. Where people make decisions about childbearing at all, they aren’t made on the basis of maintaining a stable population. Further, if life extension also extends childbearing years, then we might reasonably expect the birthrate to increase because people will have more options for balancing childbirth, childcare, and employment.
