But maybe not even then. You vote for the candidate that can best convince you to vote for them. So this is the metric the system will optimize for. Politicians that make good decisions or stick to their principles get outcompeted by those who focus on marketing themselves and pandering to the public. Even if you make the electorate more educated and engaged, this will only do so much to fix the misalignment of values. Unless you know a way to immunize someone to marketing completely, I see no hope for fixing voting. I infer that every democracy, as it matures, degenerates into a popularity contest.
It should be no surprise that the will of the people no longer has any real correlation with the policy voted into law by congress.
(Unless you're going to count it from 1945, in which case the real apathy hasn't started yet.)
Consistent with the golden rule of economics.
It is unlikely (and maybe even undesirable) that we are going to be able to easily overcome our inherent susceptibility to influence. Therefore if we are to improve things we must recognize that this is part of who we are, and design our institutions accordingly.
