Re:We used to have a variant of the Greek Democracy.
Not really, no. Our representational democracy was/is really very different in detail to the Athenian democracy, which wouldn't really scale. As for the suggestion its not working as well as it should and perhaps once did, I'm inclined to agree, but am awfully aware that (at least partially blind) nostalgia for how much better the good old days were is something else we have in common with 5thC BC Athens...
