The capitalist class is already in control. The MAGA wing of the capitalist class couping the Democrat wing of the capitalist class isn't a revolution, but a coup. A revolution implies a transformation in the class that dictates society, not any change in leadership.
It sounds like you’ve had your nose so buried in textbooks for so long that you can’t read the current situation, because you’re projecting what you’ve learned about prior situations in different times and different places.
I'd say you're guilty of the reverse. You have not learned from history, and because of that you cannot see how the problems of today are connected. Of course there are differences, but you have not demonstrated why these differences add up to an entirely new situation divorced from history. For example, why do you believe Allende was couped? You have not answered this, but it's core to the following point:
If we want to make the capitalist class subservient to the state, we need to elect a progressive government. That is the only way out of this mess.
You have not grasped the situation at all. Capitalists are not subservient to the state, the state is subservient to capitalists. This is not because the individuals in the state are personally handpicked by the capitalist class, but instead because whoever controls the commanding heights of the economy controls the state. A progressive government has no means by which to appropriate the commanding heights of the economy, this requires worker revolution.
You can try to convince people otherwise, but when they have similar questions to those I have asked you, and you cannot respond except by restating your hypothesis in different ways, then they will abandon your frame of view and seek those who can answer their questions. That's why Marxism-Leninism is seeing a resurgence around the world.
And yes, I am proud of myself for putting my time and money into studying socialism and organizing and educating the working class. Why wouldn't I be? All you're doing is disarming the working class and making us prey to the fascists with no ability to resist when they inevitably use their control of the commanding heights to overturn any progressive government antidemocratically.
