A progressive is someone who understands that personal wellbeing cannot be separated from the wellbeing of society, and that we are all better and stronger when we work together for the common good. From the air and water that we all depend on, to the education of our neighbors' children, a progressive understands that none is immune from the effects of community underachievement. Today's progressive understands that the individual is most effective when all in society function highly.
Basically the question is whether you adhere to the slogan, "You're on your own" or "We're in it together." The progressive believes that we're all in it together.
