it's not a random thing to demonize people for the simple choice to not have kids. corporate greedlords have been shitting their pants over the declining birthrate because less kids means less money for them. no matter who's paying to raise a kid--parents or taxpayers--that money isn't spent on kids that don't exist, and every industry suffers for it: food, medical, gas, clothing--everything
so if you already felt bad about not having kids, the goal is to make you hate yourself even more, and make having kids an even higher priority in your life. it seems like it should be about more than money, but for republicans it's absolutely not.
But with stable or falling populations, economic stagnation, such as that which afflicted Japan for a decade, limits opportunities to profit. And establishment think tanks worry about how to fund Social Security without taxing the rich.
they use words like crisis, panic, catastrophe, etc. -- it's all to scare people into thinking the world is going to implode unless everyone starts furiously having babies. the world isn't going to implode from fewer babies. profits will go down. that's it.
edit: also-- "shrinking tax base"--fuck that. tax the fucking rich
