Spirits Of Poverty In Nigeria?

Some time ago, i spoke with a relative of mine who used to campaign to people in Nigeria about the existence of the "spirits of poverty" and their activities in people's lives, he used to recommend them to pray and "cast" out these "demons" from their families.
  And i've seen and heard people singing "Me, i  no go suffer, i no go beg for food; God of miracle, na my papa o"
   It was impossible to convince him (my relative) that he imagined there are spirits of poverty because he was in Nigeria. Now, at the moment, he's in Canada, and few days ago, i asked him his new opinion about the spirit of poverty. He laughed and said "nonsense, i don't really think that there's any such thing like the spirits or demons of poverty".
  My people, there is absolutely no such demons like "spirits of poverty" If there is any entity responsible for poverty: that entity is/are the leader(s) of the countries.
  What do you expect, some greedy evil humans (in the positions of leaders) are enriching themselves with what is supposed to be used for the benefit of all people, now, the people are so poor that they need "miracles" to get food to eat, and you blame the devil for it?
  Come to think about this: is it actually a miracle to feed, why are the Americans or the Europeans not praying for "miracle" for food?
   Food is surplus hence there are obesities everywhere, so those who maintain slim figures are considered as human models.
   The holy book says: "remove the wicked from the throne, and his kingdom will be established in righteousness".
   What do you think, are there spirits/demons of poverty? comments please.
