We should move to a system where votes are weighted based on age. Up to, say, 40 years of age your vote has a weight of 1.0. Above 40 the weight should reduce linearly each year until it reaches 0.1 at the age that equals the current life expectancy. Basically: the closer you are to death the shorter you are affected by the consequences of your votes, so you should have less influence. Older people are probe to short term thinking as they won’t live to see the long term effects anyway.
