A bit, but I agree with you there. I think the average American (or average group of Americans) tends to expect far too much from their government because they have been promised far too much, for too long. It would be nice to:
a.) Spread more awareness of the realistic limitations of government and why such limitations are healthy.
2.) Encourage people to invest in their local communities- the trend away from that has led people to replace community with social media and political affiliations, and forget that you can actually be friends with someone who has different views than you.
In that sense, some kind of compulsory, non-punitive, community service could be helpful if it was implemented intelligently. However, because of point (a), it probably wouldn't be, so for that reason, I'm not for mandatory public service in America. The odds are too high that our government would get it wrong, and doing it wrong would make things way, way worse.
