Don’t fall for the propaganda - Natalist policies have failed. See also Eric’s balanced perspective above.
The propaganda is that Western Europe is better off when it isn’t as it is chaotic, filled to the brim with Muslims, effiminate Europeans, liberalism, filth, etc, whereas Hungary is prospering economically, land values, etc are all stable, and support for traditionalvalues is strong. In other areas, give it time.
The pro natalist policies have not failed. They have not resulted in a sudden dramatic upswing in births but they have raised the birthrate noticeably. Its a positive step. More needs to be done, but I definitely would not call such policies a failure.
