Do you think a married family with children is any better than an unmarried relationship with kids, if so why?

That question has crossed my mind a couple of times as well. We, as a society are still closed minded to the concept of live-in relationships. The fact that a marriage only gives you a certificate...a piece of paper stating that you are allowed to live together and reproduce kids. Doesn't mean you cannot have a healthy successful relationship otherwise. But yes,to a large extent being married and having a family brings with it a sense of security,stability and permanence.
