What is petty bourgeoisie? Who can elaborate? Thanks in advance!

Petty bourgeoisie was a popular word in Chinese mainland from 65438 to 0990. Originally the abbreviation of "petty bourgeoisie", it refers to young people who yearn for western ideological life and pursue inner experience, material and spiritual enjoyment. Xiaozi should be a person who pursues the taste of life. The petty bourgeoisie, generally urban white-collar workers, has a certain position and wealth in society, but it is still far from the "middle class"-mainly economically. In recent years, "petty bourgeoisie" is often a derogatory term, even a symbol of decadent mood. This kind of person is not enterprising, does not consider national affairs, and only pursues the comfort of personal life. Therefore, it has always been regarded as a decadent lifestyle that the proletariat cannot tolerate. A real "petty bourgeoisie" must have certain working ability, economic income, quality of life, ideological level and artistic appreciation.
