Now, instead of chest thumping and whining, it is better to accept the trend for the fact that it is, and work with the consequences. These changes reflect free and deliberate choices by people that are going to be respected because most people like progress and aren't going to go back to traditionalism or authoritarianism. Such trends can indeed have society-changing effects, since access to sex and family is one of the cornerstones of organized society, and society doesnt form spontaneously in nature. The foundational myth of ancient Rome included the abduction of the Sabine women. In ancient Athens, lawmaker Solon instituted state brothels with cheap prices for everyone. Marriage, and access to family for most men has been holding together societies for millenia. It's only natural that men will not want to "give back" to society if they don't feel they get any benefit.
What may follow from here? Perhaps if men still want sex they could seek more gay sex - they do seem to be having a lot more fun as a group. Or perhaps men might just not be interested in sex anymore - after all there is very clear evidence that testosterone and sperm motility have seen huge drops in the past 4 decades. Americans (with their relatively macho culture) are even lagging behind in this trend away from sex -- it's likely more advanced in many other countries. In societal terms this may undermine social solidarity or lead to mass exodus to new enclaves that have yet to be built. There's also the prospect of biotechnology: we can already almost design babies, and maybe we are not very far from an artificial uterus which at least can provide access to family for most men.
I think as societies we should not be hiding these issues under the rug (or purposely removing topics from the frontpages) but realize that these are solid, future trends that deserve being discussed reasonably and dispassionately
