Countries will have to adapt to lower or even declining birth rates and deal with it. The world cannot just keep on growing indefinitely, unless we populate Mars or whatever. The UK, Korea, El Salvador, Israel, Netherlands, Rwanda, etc., will have to learn to make their economies work with a steady state workforce even a shrinking workforce ala Japan.
Definitely, but the economies will likely won't be able to sustain your current style of living. Say goodbye to your electronics (including the one you are reading this comment on). Return to something closer to an agrarian economy until the birth rates go up. Will we agree to do this?
