The world is a wonderful place, but we are fallen children of Eve banished to a vale of tears. This world will always be inseparable from the ever-present reality of corruption and sin and all we can do is trust in God and do our best to live virtuous lives that are pleasing to him. It is not for this world that our ultimate hope is placed.For a world that is so religion-saturated (Abrahamic faith-based to be specific) ...why is there so much poverty, hatred, violence, bigotry, chaos, war, immorality, oppression, and greed?
Of course, it is good to work for the betterment of society. And religious conviction has driven countless of people to do just that. But the truth is that there will always be problems and no amount of religion is going to change that.
I also question your assertion that the world is 'religiously saturated'. The West for example has largely abandoned the principles of religion and yet, many of the big problems of our society don't seem to be improving at all.
