Democracy and Economic Ignorance

I see the Guardian is arguing that many voters don't understand basic economics concepts, and that this undermines democracy.  It is hard to argue with this.  It also affects Council consultations such as the recent one on the budget.  If you are not especially interested in local government, there is no reason for you to know what a small proportion of a Council's income comes from Council Tax, or what the effect of various back office cuts are, which tends to undermine the effectiveness of consultation.
