Yeah, less kids are being born because the media is turning people gay. That's what's happening.
I hope you're trolling.
Obviously the reason for less babies being born is primarily economic. Women are in the workplace now because you can't support a family on one income anymore and it's not a good to have kids at age 19 or 20.. They're going to college and into the workforce and having kids when they can afford them, which is usually in their early 30's. Men too.
The people having kids at a young age are disproportionately of low income. So the last thing we need is "hoodrats" having more babies, increasing the strain on the social safety net.
