I know this discussion was probably not supposed to get all that serious, and that no one in this discussion was suggesting it, but if anyone is contemplating keeping the numbers down due to financial pressures:
King Chizkiyahu didn’t have kids, because he knew [Ruach Hakodesh] that they would be Reshaim, and he was punished to the point that he made sure to have children – who, of course, ended up being massive Reshaim [Brochos 10a]. Point being, G-d expects you to do your job, the rest is up to Him, and He knows how to make things work out! [Chizkiyahu’s son, although a Rasha, was a necessary link in the chain of the House of Dovid, without whom Moshiach couldn’t be born.]
