There would be a LOT less people in the world. Killers, rapists, pretty much everyone locked up for a major crime. Gone. A majority of the politicians would be toast too. They, however, would be given the chance to step down and donate all their money to the people they promised to help, but instead abandoned or threw under the bus. I also like the idea of sending anyone who's racist to their own island with other like-minded people. Cut off all communication and let them kill each other.
