Bourgeois - immensely popular term today in Russia
Do you mean semi-humorous "буржуи"?
"Буржуазия" is not so popular term now. I think it may appear in rhetoric of modern communist party due to historical connections, but it is not widespreaded.
"Буржуй" as semi-humorous description of business class with connotations to "exploitation of the working class" can be met in inofficial speech often, yes...
