The young will experience the effects of policies passed today for the greatest length of time but this is not reflected in their voting power. Put differently, the time-horizon of (self-interested) older voters is short so perhaps this biases the political system towards short time-horizon policies such as deficit spending or kicking the can down the road on global warming. Philosopher William MacAskill offers an alternative, age-weighted voting. one way of extending political time horizons and increasing is to age-weight votes. The idea is that younger people would get more heavily weighted votes than older people, in proportion with life expectancy. A natural first pass system (though I think it could be improved upon) would be: 18–27yr olds: 6x voting weight 28–37yr olds: 5x voting weight 38–47yr olds: 4x voting weight 48–57yr olds: 3x voting weight 58–67yr olds: 2x voting weight 68+yr olds: 1x voting weight
