IMO, a better lens by which to examine human preferences is to take the position that humans are poorly evolved for modern life and that what we are witnessing right now with regards to plummeting birth rates is selection pressure which will force the human race to evolve immunity to modern life. As best as I can tell, the version of the human race that will result probably looks a lot like the fundamentalist religious sects that have high birth rates (Amish, Haredi, Mennonites, Hutterites, etc.). And the very poor.
