I believe that the United States is heading in this direction ^. We are already below the replacement rate of 2.1 children per couple. If you'd like to learn more about this, I have found an interesting article on this subject. Keep in mind, it was written at the start of the 2000 decade. Below is an excerpt where he described this very scenario happening down the line. And he was right.
Link to full article. Yes, its long. It is intended to be read in several sittings. This article is very astute in how it uncovers the fallacies behind feminism and how the it was never about being equal sexes, but more about women getting the upper hand. I can hear the white knights already coming to the rescue of women. They should think differently after reading this article.

I am working on a theory that less people are frequenting bars than they used to. Partly because the males stay at home and masturbate to pornography, partly because they are intimidated by women or tired of putting up with their shit and also because the females stay at home and simply post up pics on dating sites and then sit back and watch the worshipers roll in. They don't even have to get dressed up to have their egos stroked. I did an experiment where I created a profile and posted up a fat chick's pic. Within 24 hours, there were over 100 messages of men trying to contact me. Insane. I recently went out to the bars in Huntington. It was pretty happening, but as I started talking to people, I began to realize that it was actually dying out there too (it's been dead in my town for years). Everyone I talked to said it used to be way better with way more people. Go figure.
