Drake saying no to the conventional class system of lower, middle and upper class, but saying yes to the marxist distinction based on one’s ownership of means of production and the ability to profit off of another class’s labor.
Proletarians sell the value of their labor to bourgeois who profit off of the excess value the workers produce, and typically own the means and infrastructure of production, be it a factory or a farm, or in more recent and digital times, usually the “Cloud”, ad space, the social media platform (youtube, facebook, twitter), and digital marketplace (Amazon, who has monopsony power on digital sellers)
Basically the labor aristocracy. Those that still sell their labor to the bourgeois, but earn enough to live comfortably in the system and have aligned their interests with the bourgeois because “one does not bite the hand that feeds them”
And "middle class" could even go further to describe them as being labor aristocrats until they retire upon when they become petite bourgeois renting out their family homes to the working class. They straddle the class line.
