Even the most inpoverished will still have faith in dieties and spirits. They give thanks for their survival, and each loss makes others around them even more celebrant about the life they've come to enjoy in the weeks and months and years to follow.
If we were to look at this from a purely Biblical POV, we would see that the Earth is not the domain of God. It is His creation, but has since become the domain of Satan and his minions. (Job 1:7 shows that the devil walks the earth. The Book of Solomon identifies Satan as the bringer of death. He is called the "prince of this world" in John 12:31 andd 14:30. Matthew 12:24 calls him the "ruler of demons" and 2 Corinthians 4:4 calls him the "god of this world."
It is also idenitifed in the Bible that demons hold sway over whole places, whole cities, states, nations and large regions of this world (Ephesians 6:12; "For we wrestle not against flesh and blood, but against principalities [a term still applied to regions and political realms] and powers, against the rulers of darkness of this world, against spiritual wickedness in high places."). A modern explanation of this concept is found in the books "Spiritual Warfare" and "Warfare Prayer", which identify various places needing missionary aid to combat the evil powers (including several right here in the US) and how to conduct "strategic prayer".
In the end, however, it is up to each man to take control of his own life and destiny. 2 Corinthians 12:1-11 identifies that all men are granted gifts of God. "The manifestation of the Spirit is given to every man to profit withal" (2 Cor. 12:7).
If a people come together to combine their spiritual gifts in concert and harmonious action, they will overcome even the greatest of poverty or drought or famine.
It is the Devil and his minions that divide us. Thus some have translated his name to mean the "accuser".
