I don't see that the left has a concept of what we want as an alternative economic and political system, so that means no revolution.

i think we may not need a new economic system, but rather the present one managed accountably and transparently.

similar with democracy, a good idea in theory, but so far only created in ersatz versions, just real enough to pass fake muster, but in essence parodies, facsimiles ever more lacking in verisimilitude.

no need to re-invent the wheel, but rather to attach it to useful vehicles, like public transport, agricultural tools, etc instead of the equivalent of just military vehicles or cattle cars.

The power of knowledge is in mortal combat with the knowledge of power. It really is that simple... That's the Edenic apple we are all munching on.
