I agree in theory, but I’d require a detailed plan for what comes after legally, so as not to just invite a new breed of corruption to take the place of the old.
the senate just shouldn't exist; it exists to give slave states a veto over any democratic majority. unicameral proportional legislature would be orders of magnitude more democratic than what we have now.
courts and judges are mechanisms of state power that enforce property relations and class hierarchy. as a first step i'd like to see restorative/transformative justice approaches instead of punitive and community accountable practices instead of state violence.
as for the supreme court i don't think it needs to exist with a bunch of life-term assholes in robes appointed by politicians making the calls. randomly select large panels of citizens for each case, like it's a jury but for constitutional questions.
