So why do people have children? Why do they have more children in one country and less in another? Take Germany: We have a retirement system that people believe in (I am not saying it is working) and we have less than 2 children per couple on average. In other countries children are your retirement fund. So what if every country had a retirement fund system, that people believed in? Wouldn't that solve the growth problem? Wouldn't that be good for the world to have faith in retiring?
