Jonathan Swift said this quote

They look upon fraud as a greater crime than theft, and therefore seldom fail to punish it with death; for they allege, that care and vigilance, with a very common understanding, may preserve a man's goods from thieves, but honesty has no defence against superior cunning; and, since it is necessary that there should be a perpetual intercourse of buying and selling, and dealing upon credit, where fraud is permitted and connived at, or has no law to punish it, the honest dealer is always undone, and the knave gets the advantage.
