Luckily, there is a countervailing trend, identified by Prof. Arthur Brooks, which I’d label the “Portlandia” trend. What it amounts to is that white liberals aren’t having kids, but conservative Christians are.
Nice dream, but it doesn’t make a difference. Because each generation is still more liberal than the preceding one. This is why kids today have no problem with homosexual pseudo-marriage.
It doesn’t matter so much who has the kids if the liberal society is able to brainwash them.
