Byline: GUEST VIEWPOINT By Joe Stone
Ancient Greece brought more to the world than Homer's epic story of Troy and the Trojan horse - the story that is the origin of the dictum, "Beware of Greeks bearing gifts." Ancient Greece did no less than invent democracy.

We all face similarly vexing contradictions between the reality of scarcity emphasized by economists and the promise of plenty from politicians seeking election. The contradictions are particularly troublesome because they are so easily ignored in the near-sighted world of electoral politics.
