The Rich and the Poor

The rich, afraid that they'll be seen as the others, the foreign, the disconnected from the real difficulties of life. And thus that they will treat any of his actions with cynicism, with disdain. That they'll think of his offers to help as pathetic pity, or as a desire to manipulate them later on. Or even if an offer is truly sincere and selfless, that it be seen as "spare change", for "he has so much, this is nothing for him". That they will blame him for what he chooses not to give. 

And if he thus thinks, or is thus attacked by others, he easily closes his hands and his heart in self defense. 

The poor, afraid that they'll be discarded as the worthless, the unimportant, or the incapable of caring for themselves in the basic fashion. Afraid of being measured by wealth, they react defensively by closing their ears to advice, by insisting their situation is part of their identity, and gather in groups to reinforce each other's certainty of their correctness, reassuring each other that their situation is acceptable and inevitable, even if it is despised and complained about. Team scapegoating.
