The term nouveau riche (French: “new rich” [nu.vo ʁiʃ]), describes rich people who acquired their wealth within their own generations; the equivalent English term is (the) new rich or new money (in contrast with "old money"). Sociologically, nouveau riche describes the man or woman who previously had belonged to a lower social class and economic stratum (rank) within that class; and that the new money — which constitutes his or her 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 effects 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 new-rich man and woman who lack the worldly experience and the system of values of Old Money, of inherited wealth, such as the patriciate and the gentry.
The idea of nouveau riche dates at least as far back as Ancient Greece (c. 8th century BC). In the 6th century BC, the poet and aristocrat Theognis of Megara wrote how “in former days, there was a tribe who knew no laws nor manners ... These men are nobles, now, the gentlemen of old are now the trash.” In the Roman Republic the term "Homo novus" ("New Man") carried similar connotations.
Social status 
Social status is defined in relation to wealth, and the power granted by the wealth. Hence, the upper, ruling classes have legitimized “ . . . their rule with claims of status and honor and moral superiority.” Ruling classes make claims in defense of the ascribed superiority of wealth inherited through “blood . . . and the concept of proper breeding.” The Nouveau riche man and woman are juxtaposed against the people of the Old Money social class; and with trans-generational, inherited wealth, in order to highlight the cultural, value system and societal differences, between the two social groups within the class.
Old Family ties, as traditional claims of status, are not found in the nouveaux riches, which challenges and ultimately redefines social traditions and values such as the institution of debutantes and their debut to society. As seen through the rise in the number of debutantes, the social value of the debut has since shifted from the “family’s elite social standing and long family traditions” to “a symbolic value as an element of upper-class life style.” This transition allows for high social standing to be established by the nouveau riche through the institution of the debut. Social integration of these elite sects is extremely slow and sluggish, which prolongs and strengthens stereotypes. This rate of integration makes it more likely that the nouveaux riches will “retain identification with the traditional…group of origin; this is the basis for division between the groups. Furthermore, the isolation that minority nouveaux riches experience within their own class leads them “to prioritize issues of radical justice, civil liberties, and religious tolerance over pure economic self-interest”
Inter-class stereotypes 
Often referred to as parvenu, members of the nouveau riche are often discriminated against by the "Old Money" sects of society since they "lack the proper pedigree." These newcomers to economic freedom are subject to even greater scrutiny from their lack of historical prestige as seen through Dye's comments which reference the new rich as "uncouth" and "uncultured." The behavior of the nouveau riche is often satirized by American society by "implying that stereotyped, rather than real, behavior patterns are copied." Many people have made claims to the inferiority of those with new money as compared to those with old money. Many have made claims that nouveaux riches "lack political and cultural sophistication" and others make comparisons saying that the old rich are "more sophisticated than the less cosmopolitan nouveau riche." These assumptions further perpetuate the differences between the two and lead to even further stereotypes and have lasted for well over a century. In the 1920s, Mrs. Jerome Napoleon Bonaparte protested that "the nouveau riche... is making places like Palm Beach no more exclusive than Coney Island. Newport, the last stronghold of the elite, has the moneyed intruder at the gates.... Undesirables are penetrating everywhere."
