Sure it can. Take north western Europe, notoriously secular (when compared to the US) yes quite socialist with an extensive social safety net. Economics, sociology, etc, all help you identify what you need to do to reach what ever goals you are aiming for.

And ethics and fairness have been studied and are well known in other social species, like the great apes. They are not uniquely human.

Morality is just the formalization of a whole set of instinctive emotional desires for fairness. Most often it is enforced by using another emotional foundation, the respect for alpha leaders, as in it is God's law you do this and that.

There is no domain which will eternally be out of the reach of reason and science, not morality, not love, not spirituality, nothing. I find this wonderful!
