Impose voting rights restrictions that reduce their access. Take the average life expectancy in your country, reduce the number by whatever the voting age is in your country. Cut off their right to vote by that number.
In the USA, where you can vote at 18, if the average life expectancy is 81 (made up a number), voting would end after 63. Pretty good way to ensure longterm thinking prevails.
