The “common good” in bourgeois democracies is the good of the capitalist class at the expense of the working class.

Wikipedia: Bourgeois revolution

Bourgeois revolution is a term used in Marxist theory to refer to a social revolution that aims to destroy a feudal system or its vestiges, establish the rule of the bourgeoisie, and create a bourgeois (capitalist) state. In colonised or subjugated countries, bourgeois revolutions often take the form of a war of national independence. The Dutch, English, American, and French revolutions are considered the archetypal bourgeois revolutions, in that they attempted to clear away the remnants of the medieval feudal system, so as to pave the way for the rise of capitalism. The term is usually used in contrast to "proletarian revolution", and is also sometimes called a "bourgeois-democratic revolution"
