It's an interesting demographic problem: how do you encourage people to have enough children that the working-age population doesn't decline so quickly that we can't support our retired people and also have a wider effect on the economy? In the long run it's something that we'll have to deal with. China is starting to experience it. I think that the populations of developed countries will start to decline, and a gradual decline is acceptable. We can't rely on immigration forever, presumably less rich countries will start to have less children too as they modernize.
