What do you call a person who achieves lots of money without working, just sitting at home lending people money with the agreement that they will pay him/her back a very much larger amount of money in a specific time in a written or verbal agreement?
Meanwhile, how shall I allude to such action in normal English? (Please note that aside from a true person, a legal entity like: banks, government related organizations etc. can do the same thing.)
Does it sound natural to say: "They offer usury"?
