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)
