@Aether Paying people money to have kids will not solve the issue of people not having kids because a lack of money is not the actual reason they are not having kids. Every mouth breathers talking about "the bad economy" as the reason never have any examples of a "good economy" where people are having many children. And no, going from 1.3 children to 1.7 is not a boom in fertility.
People who want children find a way to make it happen.
