Usury (pronounced /ˈjuːʒəri/, comes from the Medieval Latin usuria, "interest" or "excessive interest", from the Latin usura "interest") originally meant the charging of interest onloans. This would have included charging a fee for the use of money, such as at a bureau de change. After countries legislated to limit the rate of interest on loans, usury came to mean the interest above the lawful rate. In common usage today, the word means the charging of unreasonable or relatively high rates of interest. As such, the term is largely derived from Abrahamic religious principles; Riba is the corresponding Islamic term.
I have posted many storiesabout how money turns evil ...
many people may says that capitalism is not good because the rich gets richer ... actually its not the capitalism, its just the way the money is defined.
Again ... its all about a large population of under educated public being abused by a small group of smarter people.
This problem has been known LONG ago and well documented almost in ALL kind of religions ...
