<<How can you believe in "people malliability" and also beleive in "revolution"?>>
No paradox at all, plane, but it's a good question. Because the people are malleable, it's easy to get the masses through various devices (religion in the old days, MSM now) to ignore their own best interests.
Revolution is not made by the proletariat as a whole but by small, class-conscious, tightly disciplined revolutionary vanguards, who need to counteract whatever stupefiant the ruling class is currently using to drug the minds of the masses, and they then need to educate the masses as to the realities of the class war, enlist the enlightened members of the proletariat and finally to bring about the revolution. In the past the main agent of the vanguard element was the Communist Party - - they attracted the best and the brightest (and also the most courageous) because they had a theory and a plan, party discipline and (I'm coming to see this more clearly now) amazingly intelligent, resourceful, far-seeing people of great judgment and vision. I might be coming around to Thomas Carlyle's "Great Man" theory of history, because you have to wonder, where are the Lenins and Trotskys of today? Probably they were the kind of individual who, like Winston Churchill in the capitalist world, comes along but rarely, maybe only once in a lifetime, once in a hundred years.
Anyway the key concept to grasp is a malleable people often fooled by the ruling class but producing a vanguard that breaks free of the stupefiant (in Marx's day, it was religion, the so-called "opiate of the people") and takes the necessary steps to throw off the ruling class and bring the "People's Revolution" through to completion.
