No absolutely, I talk about capitalism because that's the current rule of the world, but this exploitation predates capitalism by millennia, you're right. The specific aspect of capitalism or feudalism, or any such form of exploitation, is that power doesn't represent the population's interest (even though of course we pretend to live in a perfect representative democracy). If the state protects private ownership by law, and that private ownership gives you incredible power itself (being in control of production, but also media and culture more broadly), you end up with the self reaffirming loop of protecting owners, and not the population.

As an individual, you can have power over me if you hold a gun to my head, but it's virtually impossible to point a gun at an entire nation when it's that same nation that must hold the gun. Capitalism today is a massive ouija board, where anyone doubting the mystical forces is shamed, ostracized, or worse (of course this was much more literal under God's mandated monarchs). But at the end of day, this still requires wide consent, even when enforced militarily.

Another way to put it is that while we often center the conversation around the "conflict of interest" that accompanies power, we ignore what that interest is. If exploiters or their defenders are systematically put in power, they expectedly defend exploitation. The scary communist motto of the "dictatorship of the proletariat" is about recognizing the origin and importance of power in the short-term, and giving it to those whose interests are emancipation. I fully agree with you, personal gain doesn't automatically go away if you get rid of profit, but thinking about this not in terms of conflicts of individual interests, but conflict of class interests allows us to dispel the misleading scary and brutal image of power wielded in any other way than the liberal democracy. The goal of course is a real democracy, one where workers, instead, defend their interests. The expected outcome is the dissolution of that exploitation through the dissolution of class, and eventually the dissolution of the state itself.

None of this magically protects you from acts of corruption or abuse, this is why the communist approach is not to flip the table over and bring a new ouija board except this time with "the good spirit" inside, but to create class consciousness, to dispel the lies and manipulations (because we're not naive and pliable, the manufacturing of consent is a massive global industry), and to continue collectively educating ourselves as we progress so we don't get fooled when someone brings a tipping table.

I swear I'm trying to be brief 😭
