I remember bringing up the German prostition/unemployment angle to some liberal family members last year.... they were stunned to learn that this “legal” occupation could be used to hinder unemployment benefits. (I just gave them the standard “unintended consequences” line).
Nil erit ulterius quod nostris moribus addat
posteritas, eadem facient cupientque minores,
omne in praecipiti vitium stetit.
- Juvenal
To these ways of ours Posterity will have nothing to add; our grandchildren will do the same things and desire the same things that we do. All vice is at its acme.
