The Luxury of Decency.

Justice, fairness, kindness, goodwill . . . these are things we take for granted. The poorest residents of the slums and shantytowns of the world are too busy lying to their neighbors and exploiting each other to enjoy any relationships; even children are valued according to the amount of money they can contribute to the family-when they become to expensive, death (sometimes self-inflicted, sometimes not) is likely to occur. Poverty forces the people to do whatever they can do to make money-there are no limits; no lines of decency, morality, or trust that can't be crossed.
Even in much more prosperous circumstances, people are often willing to sacrifice true affection and friendship for the sake of money.
