I just finished A.J. Jacobs' 'The Year of Living Biblically,' which recounts his adventures living strictly according to every law found in both the Hebrew and Christian testaments. When his wife becomes pregnant and asks him to swear off booze with her, the biblically mandated rules concerning alcohol consumption become an issue. He decides that scripture ultimately favors imbibing but agrees to water down his wine a bit.
There was a time, not too long ago, when if someone loaned you money and charged you 29 percent interest they'd probably be called a "loan shark" and hauled off to jail. That term, loan shark, is one you don't hear much these days because the practice of usury has gone all respectable on us. It's no longer the neighborhood wiseguy or shady character who employs it — it's used by the bank down the street as well as most major U.S. lenders who issue credit cards.
