I don't know. Did people do this in the midst of world war 2, for example?

Tough to say. It was difficult to have children in the middle of WW2 when all the men of appropriate age were fighting on the frontlines.

The results would also likely be skewed by Germany quasi-forcing people to have children in support of the party.

I am not sure. I was not alive during world war 2. I would think, though, that during world war 2 it was relatively easy to think that we just need to wait until the bad guys are defeated. Now the rise of dictatorships and populism makes me wonder whether humanity as a whole is not just too stupid to survive.

The war was likely to eventually end. The price of food will continue to increase exponentially, at some variable rate of inflation, forever.

Skilled professions were likely to remain useful after the war. AI makes their future value seem uncertain.
