I was pondering, there is a reaction for every action. After being hit with so much greed and selfishness, it's contagious, hardens people, and spreads like a virus.
Would a large enough crowd, and we are talking a percentage of the world, publically announcing their disgust with their own lives being run by those things, and leading by example, could start a chain reaction of guilt and everyone seeing the positive result wanting to be a part of this, changing themselves. Very unlikely, would take such a big amount of positive energy and a shock value and large enough crowd, where everyone in the world would have some within their own network involved.
