when they say "everybody has a role to play"...

...they are right, literally. Though this line is often used because of its political correctness.

Despite one giant scandal after another that blew through news headlines over the past two years, economist Dan Ariely told us the largest damage to the economy/business world comes no from a single super-greedy fraud or Ponzi scheme. It's from thousands and thousands of little "misconduct".

Same thing to the honorable & ethical efforts to change the world. Despite our hero complex, real changes are results of millions of tiny little consistent acts by thousands of seemingly insignificant people.

If you aren't those who occupy headlines all the time, it's about you and me.
