People used to retire by having a few kids who would take care of them.
I prefer shrinking our population, especially as developing countries are rapidly growing.

FWIW, I think people tend to overstate the risks of overpopulation; the Earth could support 10x the current population with a comfortable standard of living, if space and energy usage per person was reduced (which could be helped along by increased urbanization, among other things).
It is no coincidence that the human population has doubled sine 1970...while the number of wild (non-domesticated) animals has halved.
So sure, we might be able to support 80 billion (!!) humans...but with a correspondingly devastating loss of biodiversity.
You don't need population growth for economic growth. Technology is sufficient.
