Whenever there is a demand for credit, there is a demand for usury. The lending of money represents an initial net loss of capital and opportunity to the lender, since he has less money of his own to spend and invest. Therefore, it is both legal and moral to charge interest on a loan to compensate the lender, provided both parties agree to the terms.
Can someone explain why this is still not understood. How are there still people against charging interest on loans?
