"Le Bourgeoisie" is, after all, a French word.
"In Marxist philosophy the bourgeoisie is the social class that came to own the means of production during modern industrialization and whose societal concerns are the value of property and the preservation of capital, to ensure the perpetuation of their economic supremacy in society."
--From Wikipedia
But Marx is a century out of date, and he never imagined what is happening today. The Bourgeoisie have little to fear from a revolutionary proletariat, their new nemesis is the financial elite, an offshoot of their own class, those who own nothing except equities.
