@QasimRashid IMO it's true both that
1) the state is primarily an instrument of ruling class power and genuine democratic control on a stable basis is impossible, and
2) it can respond to sufficient mass pressure from outside, on a short-term basis.
So the best approach is arguably to focus pressure on specific reforms that don't require ongoing democratic control of the state to administer, like allocating tax money does.
So we should eliminate or weaken as many as possible of the legally-enforced mechanisms by the ruling class extracts economic rents from artificial scaricties and artificial property rights (intellectual property, absentee landlordism, subsidies to operating costs, etc.). And we should build into the system a basic income guarantee that functions automatically without a need for ongoing appropriations (like a negative income tax that would bring everyone above the poverty level for less than is currently spent on welfare).
Billionaires woudn't exist if they weren't able to extract monopoly incomes with the help of the capitalist state.
