I think we shouldn’t underestimate human empathy. The problem is just that we build structures to avoid it. Rich people choose to not see poor people too much or they would feel empathy and be inclined to help them. If the poor are far away, merely an abstraction that is said to exist, then their existence is not felt strongly enough to trigger an empathy response. Surely there are exceptions to some degree, but I think humans are very empathetic and that’s one of our great powers.
