Douglas Adams on democracy

"'It comes from a very ancient democracy, you see...'
    "'You mean, it comes from a world of lizards?'
    "'No'" said Ford, who by this time was a little more rational and coherent than he had been, having finally had the coffee forced down him, 'nothing so simple. Nothing anything like so straightforward. On its world, the people are people. The [political] leaders are lizards. The people hate the lizards and the lizards rule the people.'
    "'Odd,' said Arthur, 'I thought you said it was a democracy.
    "'I did,' said Ford. 'It is.'
    "'So,' said Arthur, hoping he wasn't sounding ridiculously obtuse, 'why don't the people get rid of the lizards?'
    "'It honestly doesn't occur to them,' said Ford. 'They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates to the government that they want.'
    "'You mean they actually vote for the lizards?'
    "'Oh yes,' said Ford with a shrug, 'of course.'
    "'But,' said Arthur, going for the big one again, 'why?'
    "'Because if they didn't vote for a lizard,' said Ford, 'the wrong lizard might get in. Got any gin?'"
