Rich people are not a species. It depends on the person, of course they could feel empathy for the poor its just the arrogant ****ers that don't help.
Empathy isn't being able to understand as much as it being able to feel, actually feel, how other feel. To put yourself in their place emotionally.
A complex form of psychological inference in which observation, memory, knowledge, and reasoning are combined to yield insights into the thoughts and feelings of others, and experience similar feeling.
Well, That seemingly simple question is actually very hard to answer. :-)
That's like me saying: "Hey, I've never eaten an orange... What does it taste like?" You wouldn't be able to answer.
It feels.... Sad?
I feel as I would feel if the same happened to me I suppose. It would be easier to answer if I felt empathy to you in person.
