Nail someone to the floor, hungry, unable to empower themselves, and they're forced to listen to your sermons. No where to go, no way out, of course you're more likely to come to believe what they say than someone who has the freedom to painlessly get up and walk away, without having to tear nails out of their limbs. Poverty is a trap that you are meant to die in, and indoctrination is a tool of oppression.
