What's wrong with a country having its population getting lower in an overpopulated continent? South Korea is a highly educated and developed country and most families are very well happy with a single child.

With the advancement of technology, robotics, AI and so on I don't see how manpower is going to be absolutely necessary in the future either.

If the problem is retirement and how to finance it, don't worry, alternative ways exist to fix that, fearmongering isn't necessary.

No, you are not a "racial supremacist" if your goal is to keep social peace and prevent the society you live in to crumble with millions of individuals who don't share the same values as you. Death to the merchants.
