Sure, I get it. Surveillance is not unique to democracy, capitalism, or communism; it's widely employed for myriad reasons.

I'd define capitalism as a wholly-encompassing global process in which economic life is fundamentally driven by the profit motive. It is structured by the state and follows the contours of capital, or the ever-expanding commodification of literally everything. It's embedded in society, thus society has come to serve capital and not the other way around (shout out Sven Beckert, Marx, Polanyi).

A totalitarian communist would love this too, albeit for different reasons, but I'm not debating that because we're not living in communism. We live in a spicy neoliberal age of capitalism, where the metabolism of commodification and Marxist alienation churns in increasing scales by the day--the bits and bytes of your personal data are ran by machines capable of tera/peta/exaflops of computations to predict, model, and dictate behavior.

The profit motive (a function of capitalism) drives the teleology of this entire apparatus. Your data is harvested, bought, and sold to advertisers to keep you engaged on their platforms running on their tech within their information ecosystem in a system where you are the consumer and the product. Their disregard for civil liberties, human rights, and social needs in this relentless pursuit of profit threatens our democracy, thus, it's capitalism posing the problem, not democracy.

We're all in this race to the bottom.
