What is the value and worth of children in such a society?
At the end of the day, other peoples kids, raised and brainwashed in public institutions, will take care of those who decided to have no children and live into the day. Socialism tears out the foundation of any society, the family and children. But this is a long term consequence.
In the little town I grew up in, Walldorf Germany we have three swinger clubs. There older people, mostly childless or at most with one can get their hedonistic pleasure. Who wants kids? They cost money, time, impede one’s career, commit one to another person, and social as well as sex life!
