Why would there be a concern for overpopulation? Population is falling in every developed nation now, if you ignore immigration. People don't want to have a lot of kids when they have money and education, and this is happening to every nation as it develops. >If we still had a significant population of people born in the 1700s, what might U.S. politics look like? Not that different, because 1) there just weren't that many people alive back then in the first place, and 2) most of them would be dead anyway, because immortality doesn't make you impervious to accidents, murder, tornadoes, etc. Even with immortality, people are eventually going to get killed somehow.
