There are most likely some people who would want to have kids under those circumstances. To the extent that the traits that lead them to act that way under those circumstances are heritable, either genetically or through parents-raising-kids (some religions are obvious candidates here), these traits would be selected for in subsequent generations. If a supermajority of people lack these traits, the problem may be put off for some generations, but eventually it will make itself felt. That said, I think there are a few possible solutions, and I certainly am in favor of developing immortality.
