Mr. Happy's observation is sound. Of course we have to be kept in fear of our politician's motives. If we looked at them with the same practical viewpoint, we'd understand that they are just as human as us and therefore fallible. Giving our trust to them means we don't have to make the hard choices ourselves - and relying on an idiot is easy to blame.
And as mthrurston put it, we are lazy - we want to appoint others to do the thinking so that whenever there is a problem we can have someone to blame, and not ourselves, when the problem goes awry.
I also like the observation of mthurston that the lying gives support to funding. That is apparent in every aspect. Take, for instance, the hype on the swine flu. Who is ultimately benefiting from a "pandemic?"
