I’m having trouble seeing why population decline is a real long term concern.
Yeah sure, short term economic costs, loss of power for the elite, some minor national security issues but for the day to day people, there isn’t a single scenario other than keeping other powers off of your cultures lands where a population decline doesn’t make life better.
Loss of 90% of the human race over time would leave us with a global population around that of 1700, one of the more productive times in human history. I suppose if too many of these people were Sub-Saharan Africans or other Low IQ/High Time preference types it could be an issue but otherwise who cares.
Less people, a better life for everyone else.
This optimistic view fails to account for the fact that the lower classes get their political power through force of numbers.
If the population gets crunched, the lower classes will suffer the most, and the upper classes will kill off the rebellious ones first.
Note that the people who are failing to breed are often the progressive intellectuals with high IQs. The people who are breeding are usually semi-literate or illiterate.
A decadent power elite is not going to be full of freethinkers and critical philosophers. It is going to be full of obedient sociopaths who “fail upward.” The honest critical thinkers are going to get killed off before they get a chance to pass on their high-IQ genes.
Furthermore, the 21st century has lots of robots and automation. This means that no matter how far the population falls, it’s not going to increase the wages or social power of the working classes.
Population collapse is dysgenic (usually).
Some population crashes probably were not dysgenic. The Black Death in Europe, whether or not it was dysgenic, led to more power for the lower classes. However, that was because wage labor was very important at that point in history.
However, many population crashes are disasters. The most able members of the population are often sacrificed first.
Consider the case of Britain in World War I. The most healthy, self-sacrificing British men walked obediently into machine-gun fire. The least healthy, most selfish British men were left behind to try to breed. Many British women turned to lesbianism. The power elite consolidated its power over the lower class. Nothing good came to Britain from that debacle.
