You need to start thinking in materialist categories. "Order" in society does not exist as a universal principle, it is always the byproduct of concrete interests with concrete means to enforce them, and the fundamental nature of the social order depends on and changes with what these interests are. Once you know this, you can understand the dialectics of society and convince yourself that only the lower class can and must be the motor for fundamental social change. The role of protest is not to create further "order", but to articulate the interests of the lower class and sections within it, to mend its internal divisions, and to precipitate the changes its interests necessitate.
