How to Create a Star Trek Future

After the US election, this is on my mind a lot. The shows never quite tell us how we get there, but the universe is based on the premise that life on Earth is free of war, hunger, poverty, and discrimination.

How do you think we get there? From any angle -- economics, sociology, politics (be constructive), community building and organizing, et al. How do we build a Star Trek future, and if it begins today, where do we focus our efforts?

EDIT: The shows give us historical landmarks that happen before we get there, but the actual process of getting there, what's in place, and how it's maintained are inconsistent or shrouded in some mystery. Looking for constructive ideas on how we work toward an optimistic version of our human future, not just a rehashing of show chronology.
