You small minded people should really get out of your little cardboard box once in a while. Usury is a no no in many religions but still happens.
"Usury (in the original sense of any interest) is scripturally and doctrinally forbidden in many religions. Judaism forbids a Jew to lend at interest to another Jew. It's forbidden in Islam. The most recent Catholic teaching on usury is by Pope Benedict XIV in his Vix Pervenit from 1745 which strictly forbids the practice, though given the modern day Catholic Church's investments in the banking industry, the prohibition has to be regarded as a dead letter.
In the modern world Islamic teachings against Usury probably have the widest influence, and specialized codes of banking have developed to cater for Muslim investors wishing to obey Qur'anic law; see: Islamic banking.
Usury has been denounced by almost every major spiritual leader and philosopher of the past three thousand years. Plato, Aristotle, Cato, Cicero, Seneca, Plutarch, Aquinas, Jesus, Muhammad and Moses are just a few.
