Well, according to one poster these are the 'ideas' we can learn.
Robert lives in an 'environmental paradise and have no need to be industrious to survive'.
Robert's running of the economy reflects the 'idea of exploiting the land more and more to feed the greed of man may in fact not be everyone's idea of "good"'.
One must not disagree with Robert because 'To think that someone is stupid because they don't think the same way as you do is to be no better than them.'
