In his book ” The Anatomy Of  Revolution” by Crane Brinton-which was written decades ago-he studies the British Revolution of 1640s, the French American and Russian Revolutions. In the book Brinton says the preconditions for a successful revolution are–

• discontent that affects nearly all social classes.
• widespread feelings of entrapment and despair.
• unfulfilled expectations
• unified solidarity in opposition to a tiny power elite.
• a refusal by scholars and thinkers to continue to defend the actions of the ruling class.
• an inability of government to respond to the basic needs of citizens.
• a steady loss of will within the power elite itself together with defections from the inner circle-a crippling isolation that leaves the power elite without any allies or outside support.
• a financial crisis.

I think we can check off some of those..headed close to some others..
