They always try to form the question in a way to make you sound like Hitler when you speak against overpopulation, it's a bit funny at this point; who should we stop? Nobody, we should just pay some fixed amount every decade or so to people who don't have children (by their own decision to do so of course), probably focused on low income neighborhoods as they are less likely to provide a suffering-free childhood, and that need the money the most. This is just an idea, the main gist is that is a matter of incentives and disincentives.
