This idea is not a new one and appears even in Shakespeare's King Lear. In Act III Scene iv, Lear also thinks about poverty:
In a moment of clarity, he suggests that the wealthy do have a responsibility to the poor. He also states that empathy is the only way for people to realize that this responsibility exists. Perhaps the only way for Singer's solution to be implemented is to increase the empathy of the country.Poor naked wretches, whereso'er you are,That bide the pelting of this pitiless storm,How shall your houseless heads and unfed sides,Your looped and windowed raggedness, defend youFrom seasons such as these? Oh, I have ta'enToo little care of this! Take physic, pomp.Expose thyself to feel what wretches feel,That thou mayst shake the superflux to themAnd show the heavens more just.
