Lesson would be that you reproduce when you live in a Commie Nation.
And when you overthrow the commiies, you stop having babies.
Not at all. You reproduce when you live in a commie nation because the State has killed so many of your countrymen and women in its quest for power that they need to indoctrinate a fresh class of children to keep them in power; so they encourage or even mandate reproduction, as Ceausescu did in Romania.
Then, when the Statist agenda inevitably fails in the third generation, there aren't enough jobs, economic strength and resources left to support a healthy birth rate.
