What should one think about the massive inequality in the world?

"... one should think in this regard about the sort of inequality that reigns among all civilized people, for it is obviously contrary to the law of nature, however it may be defined, for a child to command an old man, for an imbecile to lead a wise man, and for a handful of people to gorge themselves on superfluities while the starving multitude lacks necessities."
