Do you know what Nouveau Riche means?
Basically Nouveau riche is a French word for "new rich" or people who have got new money, which in simpler terms refers to a person who has acquired considerable wealth within his or her lifetime and is not rich from his birth. It is used for the people who were initially part of a lower socioeconomic rank, and later on after attaining wealth, they are having means for the acquisition of goods or luxuries that were previously unobtainable.
There is a great article on some of the Nouveau Riche people, who have become rich because of their entrepreneurial efforts. The article captures some of the brief life history of various such people. Although the article is dated back to 1991 but still it has some real good stuff to read. Some brilliant billion dollar business ideas. Sometimes i wish i should also get one..
