Far greater progress is to be expected from the successive rise into power and prosperity of new elements of the middle-class—and of the upper layers of the wage-earners. This is the progressive and the Laborite movement.
By far the greatest progress is to be expected as a direct or indirect result of the revolt of the lower classes. For this is the only force that can be relied upon to put an end to class government and class exploitation of industry, and to establish that social democracy which is the real or professed aim of every progressive movement.
