One great reason why the rich, in general, have so little sympathy for the poor is because they so seldom visit them. Hence it is, that according to the common observation, one part of the world does not know what the other suffers.

Many of them do not know because they do not care to know: they keep out of the way of knowing it, and then plead their voluntary ignorances an excuse for their hardness of heart.
