That's very admirable of you; I think individuals just see it as a problem which is 'unsolvable'...for a million different reasons. Like you, I have to believe that you just haven't found the right people yet. What comes to mind is one of my favourite quotes by a cultural anthropologist named Margaret Mead:

"Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has."
