> The goal is to support the needs of the population. If people have kids and kids aren't dying because of modern medicine, the population explodes It actually doesn't, though; when modern medicine lowers childhood mortality, people voluntarily choose to have fewer children. This is part of the "demographic transition" which has been happening around the world over the last 200 years. There's no need to stop people from having kids; you just stop the kids from dying, then parental investment skyrockets, and next thing you know your population's fertility level is below replacement.
