Are you sure that Bangladesh juvenile deliquency rates are all that much better then the ones in USA? Because looking at Bangladesh, they have pretty serious social problems in that area.

Strong norms in favor of marriage and strong taboos against divorce also however go with larger rates of domestic violence rates and no way out. That the perpetrators of those don't end up in jail does not make such society better behaved or less criminal/violent. Just tolerant of violence toward some people.
