Ok, so here is my idle thought for the day.
Restrict the power of people at the average age of death in their country. Be a jerk about it, no political positions, no company directorships, trust boards or any other position of power can be held once you pass that age.
In NZ that is 83 for women and 79 for men.
That is old; really old, to be making decisions about the future.
If billionaires want to retain power beyond that, better fund those works that make things better for everybody to bring up that average. Men, you will need to up your game as women out live you by 4 years or 5%…
Perverse incentives, maybe keeping people alive using machines etc, longer than in medically advisable…but that doesn’t work on the scale of millions of people.
Edit: for clarity, I am not calling for disenfranchising the old, they would still have the right to vote.


But you’re ignoring the part that they will extend the 90% lives, just not as much and at a much lower quality of life. You just focused on my last sentence.
How though?
What could both extend your life and make its quality lower. The 90% still outweigh the 10%; they are going to quickly see a major advantage to having the advances be more widespread.
In saying the above, people constantly vote against their best interests as it is.
