"Society is just as well off if people have priorities other than marriage and children."
True, but not necessarily worse... At whatever age (and if and when) you decide to have children, you will find that this is true-- your life is changed forever, you can't do everything that you want to do, all of the time, and (if you are a good parent and spouse)-- family comes first.

Oh absolutely and hopefully anyone going in to parenthood realises that.
I do not want children because I like my lifestyle and I like having dual-incomes with no kids ;D
We used to call them DINKs.
