It could be this way, this is probable. It is hard to say whether technological progress made population grow faster (at some initial point it did surely) or later the bigger population made faster technological progress. What is sure for me is that societal changes are centuries behind the technological progress. If you heard about the Polish scifi writer Stanisław Lem, I can recommend him, he very frequently was talking about it. The societal regres is because of libs and conservatives of course. Maybe we really do not need to care to much about small fertility rate in western world when the whole world population still grows. The fertility rate is a topic frequently touched by white nationalists, because they are upset that the other races reproduce more than them. I fucking hate nationalists.
