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)
I think that a middle class does exist. It's not a class in and of itself, but there is a middle strata of labor aristocrats, kulaks, managers/taskmasters, members of the security state, and various professionals (some working class, some petite bourgeois). This middle strata does tend towards reaction due to an intense anxiety towards proletarianization/expropriation, and their current relative wellbeing is intrinsically tied up with the capital order.
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.
