Nouveau riche, new rich or new money is a social class of the rich whose wealth has been acquired within their own generation, rather than by familial inheritance. These people previously had belonged to a lower social class and economic stratum (rank) within that class and the term implies that the new money, which constitutes their wealth, allowed upward social mobility and provided the means for conspicuous consumption, the buying of goods and services that signal membership in an upper class. As a pejorative term, nouveau riche affects distinctions of type, the given stratum within a social class; hence, among the rich people of a social class, nouveau riche describes the vulgarity and ostentation of the newly rich person who lacks the worldly experience and the system of values of old money, of inherited wealth, such as the patriciate, the nobility, and the gentry.
