Capitalist Christians love to cite Matthew 26:11: "For ye have the poor always with you; but me ye have not always." The saying references an older saying that capitalist Jews like, Deuteronomy, 15:11: "For the poor shall never cease out of the land: therefore I command thee, saying, Thou shalt open thine hand wide unto thy brother, to thy poor, and to thy needy, in thy land."
So long as there are natural disasters, there will always be poor people. When a disaster occurs, the victims need to helped generously, with hands wide. These sayings have nothing to do with perpetuating systems of economic inequality. They simply acknowledge that we will always need to help when help is needed.
This post was inspired by What Jesus knew about income inequality (Opinion) - CNN.com, which takes an approach that philanthropists like, but which Jesus's saying about the two mites rejects.
Luke 21:1-4 "And he looked up, and saw the rich men casting their gifts into the treasury. And he saw also a certain poor widow casting in thither two mites. And he said, Of a truth I say unto you, that this poor widow hath cast in more than they all: For all these have of their abundance cast in unto the offerings of God: but she of her penury hath cast in all the living that she had."
