promote the explosion via tax policy that subsidizes reproduction because of the short term desire to keep their Ponzi schemes going and possibly to keep the supply of cannon fodder up. Religious leaders promote the explosion too in the belief that their religion will win world domination if their members can outbreed the other guys. Pretty much the entire female gender supports fertilizing at least three of their eggs to satisfy their reason for existing (the third + spawn is a biological attempt to one-up the other guys) and the male gender goes along with it because society gives out virility points for it, even though any monkey can do it. Without women, political, and religious leaders on board it'll be a tough slog.
