In my younger days I thought direct democracy was unworkable, but now I realise that might have just been my brain conforming to the bourgeois representative government status quo.
Obviously we easily have the tech to do DD these days, everyone has a smart phone in their pocket, we could do it instantly and on the go. But how you could manage a planned economy that way I’m not sure.
We'll need to be at a relatively high stage of socialism for it to work. Everyone needs to have the same amount of free time to devote to it for everyone to have equal representation
Or at least everyone has to have sufficient free time.
