I like raising the age, i do not like mandatory government service. I lieu of military service just get a job. Work until they are no longer receiving government welfare that isn't related to an honest disability, then they can vote.

What if it didn't have to be military? What if a year in the Peace Corps, or state Conservation Corps, or working for a school district were also options? (I'm sure there's plenty of other ideas out there too).

The whole point, after all, is proving you're committed to the community.
