In the Voter ID discussion, Dirty Jobs Guy noted that voting used to be granted more to those who were more likely to have a commitment to the community. Owning property was required in colonial times and the early years of the US; in some places an oath was required. There were difficulties in qualifying to vote. One can see how that is deeply unfair in some ways, and allows landowners to perpetuate advantages. It mattered less in New England, where land ownership was distributed, than in Virginia, where the FFV's owned the land and had many servants who could not. Requiring oaths is a problem for some religious groups. There are also those who did not have fixed addresses but still provided useful service, such as sailors, small traders, or permanent military. Still, the principle remains that if people have to show some commitment, they take it more seriously.
When teaching an adult Sunday School class, we tend to find that people are more likely to attend and do the work if they had to buy the book rather than have it given. But requiring this goes sharply against the idea of a free Gospel available to all, and the kindness of not embarrassing someone who may not be able to pay but would be humiliated for that to be known.
We made education free to all receivers regardless of their ability to pay as a cultural equaliser. I think that resulted in a fair bit of gratitude for the first two generations of it, who had parents and grandparents who were painfully aware of advantages they did not have. But once it becomes automatic, the gratitude disappears. It's just human nature.
I have said not-quite-kiddingly that they should move the polling places every election, so that it takes some effort and research to find out where to vote. Part of me rejoices when the weather is bad on election day. The drive to make it easier and easier seems misguided. I don't want to keep out disabled people or young mothers carrying babies, but I do want to discourage people who just don't care that much. I admit there is a sneaky downside that the harder one makes it to vote, the more the field is yielded to fanatics of all stripes. Yet I don't think that is a realistic worry.
