Limitations of monogamy

Name(s): 
Monogamous marriage law
Claim 
The nuclear family was only sustained at the cost of sacrifice on the part of women. We need a new definition of the family, which may well be more matrilineal, certainly more diverse. It will match an era of serial monogamy in which people will expect to have two or three partners in a lifetime.
Counter-claim 
Social permissiveness positively encourages people to break up marriages, or get pregnant casually.
