Nouveau riche
Nouveau riche (French for 'new rich'; French: [nuvo ʁiʃ]), new rich, or new money (in contrast to old money; French: vieux riche [vjø ʁiʃ]) is a social class describing rich individuals whose wealth was acquired within their own lifetime, rather than by familial inheritance. These individuals had previously belonged to a lower social class or economic stratum (rank) within that class, but the acquisition of new money enabled upward social mobility.
