The future doesn't vote. And when tomorrow's generations get their turn at the polls, they won't be able to punish those who failed to consider their interests.
This makes me angry, mainly because it reminds me that I have no way of punishing people who lived in the past. If I did, I would surely fine Edith Wharton for writing Ethan Frome. But if there's one thing I've learned from watching all of the Terminator movies, it's that future generations definitely will come back to change whatever they don't like about the future.
I'm more worried by the fact that my future self can't vote today, and I might be unwittingly working against his interests, if I change my mind about things between now and then.
