To be good or generous is not a sin. On the contrary. But when the pleasure to donate money becomes an addiction, goodness is not anymore a virtue, but a habit.
Some generous people, with big hearts, who offer some from their short or overflow income to people on the street, at charity events, at fundraising or through credit cards, try to put an end to what seems to be a destructive addiction. 
Although fiction, this “how would it be if” intrigues and also satirizes.
