But the woman are childless, too, aren't they? It's not like we cultivate harems and some top 20% of men get all women pregnant. So in a sense they are surplus women and as "problematic" as the male counterpart. If this goes on for like 1000 years, we will simply go extinct. The only real surplus males here are those without a female counterpart, because of birth differences and those numbers can be handled I think.
