The way of revolution.
As per you
"there are now plenty of educated and others within the middle class to be enough to drag a politician out of a car"
if they are educated, they wont do what you suggest and if they do, what social change you expect from this sort of educated goons? Isn't you are looking to change the mindset of the people, which tends toward might is right?
The educated must educate more and change the system with their power to vote. Treat the corrupt with legal weapons, pass on the example to follow for next generation.
Anarchy can only end an anarchy to create another one.
