The cruelty here is doubled: someone who has experienced poverty themselves, who should understand it, uses whatever small power they gain to oppress those even worse off. The image of a sweeping rain is vivid — it does not just fail to nourish, it actively destroys the food supply. Oppression among the poor is perhaps the most bitter form of injustice.
Memory phrase: Never crush the already poor.
Talk about it: Why is it especially cruel to hurt someone who is already suffering?
Prayer: God, help me never hurt people who are already hurting.
