"Inheritance and morality?"......don't think many young people think about that when getting married for the first time, marriage has always been recognised as the best way of bringing up children.

Providing in most cases a secure environment.

As I have pointed out on many occasions, children and extended family encourage morality. The new "monogamy" of "open marriages" encourages promiscuity and ill health....there is no morality and society is in danger.....Children become an encumbrance.
