Petit bourgeois
Petit-bourgeois is a French adjectival phrase meaning 'of the petit bourgeoisie', or the lower middle classes. It implies conventionalism and conversatism.Although used mainly academically in the past, the term has evolved and is now being embraced by a wider group of people that opposes these values. It is often considered an ideology of its own, that considers certain values to be necessary for happiness. These include family life, economic safety and social prestige.
The opposing factions are usually associated with Cultural Leftism.
The subject has recently been popularised by the motion picture American Beauty, by Hollywood director Sam Mendes, describing life in American suburbia.
