Well, yes and no.
Stalin did encourage large families, at times when he wanted more workers and more troops. But Communism also insisted that religion was the opiate of the masses and that conventional morality was dead. Marriage was a bourgeouis institution, faithfulness was a foolish dream of the past, relegated to the dust bin of history.
Stalin also suggested that children should rat to the Secret Police on their parents, husbands should rat on their wives, and wives should rat on their husbands, because loyalty to the state superseded all other loyalties.
So, let’s not get too starry eyed about the virtues of Stalinist ideology.
I have read where Soviet pediatricians probed young children about parental conversations regarding how they view the government, turning the children into "rats". I expect this dynamic to evolve out of Obama's takeover of healthcare.
