I don't know if it would or not. I'm not so cheeky in my atheism that I assume the abandonment of god(s) would lead immediately to a better world, because I suspect some people who used to be religious bigots would simply slip into some other form of bigotry, since hate seems to come second nature to them.
Besides which, I don't think the goodness or badness of a world without religion and faith is relevant to the discussion of the existence of the supernatural. Morality and ontology are totally different here. Being a person with a vigorous need to "get things right," I'd support the eradication of superstition in the same way that I like to edit poor grammar from my writing, or correct my niece's math homework. It's like hammering in a slightly bent nail--you want to fix an error.
