"Follow the Money!"

 To quote the so-called Deep Throat (Mark Felt, who was destabilizing government to soothe his butthurt that he hadn't been chosen for FBI Director).

But, it's a fair idea. The Revolution doesn't run on Unicorn Farts. You need money - LOTS of it to:

• Transport the 'protesters' into the stages for riots. Not the people looting - they can be found in any city, for the price of the opportunity to get some stuff. But, the organizers, who coordinate the action through use of walkie-talkie type communications (can also be done peer-to-peer on cell phones, without involving the FCC-involved networks), provide the convenient gasoline for arson, sticks/baseball bats for attacking anyone walking by, bricks/rocks/skateboards to bash in innocent bystanders, lasers to blind the police, and cash money to entice locals to cooperate.
• Bail out those arrested. Focus on the people who have been brought in for the action. The hell with the locals, who know little, and are disposable.
• Pay off the local government to order the police to stand down. Those guys can be paid off cheaply.
• Provide money for spokespeople. Those are "the face" of that sector of the movement. Pick someone with a shady background - their choices for other employment are slim, so they will be anxious to keep their masters happy. Bonus: if you pick one minority/alleged minority, with a whole lot of White People surrounding her/him, you both insulate that person against criticism, but also buffer her/him with acolytes who will say ANYTHING to keep their tenuous position as a 'revolutionary' leader.

Why is Soros doing this? Well, aside from enjoying seeing the system go down, there is also the fact that he is quite experienced in making a profit from the chaos.

Win-Win.
