A man approached the rabbi and complained about the poor economic situation of the town:

“There is one thing that depresses me,” sighed the man, “and that is the injustice accorded to the poor. The rich who have more money than they need can buy on credit. But the poor, who haven’t two coins to rub together, have to pay cash for everything. Do you call that fair?”
“I admire your ideals for nature,” said the rabbi, “but a merchant who extends credit for the poor instead of the rich will soon become a poor man himself.”
“So what?” retorted the man, “Then he’ll be able to buy on credit, too!”
