Quality trumps quanity to a certain extent, past a certain point of pouplation decline we are simply stunting our own growth and leaving us open for attack.
See Rhodesia, no matter how good those Rhodies were they were trumped by the sheer amount of negros and even had to rely on Negros for simple labour and some military application.
It takes alot of men to sow a field and even more to win a war. Sure our one thousand is better than their ten-hundred but if they have a million the point is moot as it is.
We should adopt social and state eugenics to strengthen our racial stock and cleanse impure elements for the greater good; but at the current time we should not even be looking at heavy handed pouplation control or reduction.
The third world massively out numbers us, White people make up 15% of the world pouplation at most. We can't afford to lower this number even further, nor should we until we have significantly gotten the other race's numbers under control.
And economic degrowth is never needed, we just need to ensure that the economy is geared to meet a demand not generate one through materalism.
>All buisnesses in the hands of the state
There is no reason to adopt a command economy, the state can reduce production for redudant industries from a state directed economy just fine, while avoiding the impossibility that is a command economy and it's WASTE of resources to fit a demand it can not possibly guess.
