>>They intended that people with real jobs would be noble enough to sacrifice a year or two and take time off away from their farms to serve the people.
Right. Which had caused some wags to propose methods to identify the eligible citizen who wants office the least so it can be foist on them. ;-) At a minimum you can rely on such folk to do their best and get out rather than acting to preserve their career or found a dynasty.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
