Can anyone tell me, or suggest where to find information on how the poor and witchcraft are related? I might not be asking the question right (my apologies), so allow me to explain. I don't come from money, my grandparent (especially on my dads side) struggled day to day. My dads mother was widowed with 6 children of her own, and 2 family members children that was abandoned with her by the age of 31. I was raised with simple things like...chill a crocodiles tongue for insect bites. And to keep crocodile tongues by the door for burns or cuts. My entire life was filled with remedies, superstitions, lore, etc...Even to the point of doing divination with a needle and thread, and rolling an egg over a person to remove the negative. I have met others like this, and they also come from extremely poor backgrounds. Is there a connection here?
By the way... My Grandmother never called herself a witch, all she'd say is "I'm a wise old woman, that know what works".
Any book on this that might help me out?
Thank you in advance.
