Only a crisis - actual or perceived - produces real change..

“Only a crisis - actual or perceived - produces real change. When that crisis occurs, the actions that are taken depend on the ideas that are lying around. That, I believe, is our basic function: to develop alternatives to existing policies, to keep them alive and available until the politically impossible becomes the politically inevitable.”

  Milton  Friedman

(I disagree with Friedman on almost everything)

Every great cause begins as a movement, becomes a business and eventually degenerates into a racket.
