By contrast the Order of the Knights of Labor, as seen already, was governed by an all-powerful General Assembly and General Executive Board. At a first glance a highly centralized form of government would appear a promise of assured strength and a guarantee of coherence amongst the several parts of the organization. Perhaps, if America's wage earners were cemented together by as strong a class consciousness as the laboring classes of Europe, such might have been the case. But America's labor movement lacked the unintended aid which the sister movements in Europe derived from a caste system of society and political oppression. Where the class lines were not tightly drawn, the centrifugal forces in the labor movement were bound to assert themselves. The leaders of the American Federation of Labor, in their struggle against the Knights of Labor, played precisely upon this centrifugal tendency and gained a victory by making an appeal to the natural desire for autonomy and self-determination of any distinctive group. But originally perhaps intended as a mere "strategic" move, this policy succeeded in creating a labor movement which was, on fundamentals, far more coherent than the Knights of Labor even in the heyday of their glory. The officers and leaders of the Federation, knowing that they could not command, set themselves to developing a unified labor will and purpose by means of moral suasion and propaganda. Where a bare order would breed resentment and backbiting, an appeal, which is reinforced by a carefully nurtured universal labor sentiment, will eventually bring about common consent and a willing acquiescence in the policy supported by the majority. So each craft was made a self-determining unit and "craft autonomy" became a sacred shibboleth in the labor movement without interfering with unity on essentials. The principle of craft autonomy triumphed chiefly because it recognized the existence of a considerable amount of group selfishness. The Knights of Labor held, as was seen, that the strategic or bargaining strength of the skilled craftsman should be used as a lever to raise the status of the semi-skilled and unskilled worker. It consequently grouped them promiscuously in "mixed assemblies" and opposed as long as it could the demand for "national trade assemblies." The craftsman, on the other hand, wished to use his superior bargaining strength for his own purposes and evinced little desire to dissipate it in the service of his humbler fellow worker. To give effect to that, he felt obliged to struggle against becoming entangled with undesirable allies in the semi-skilled and unskilled workers for whom the Order spoke. Needless to say, the individual self-interest of the craft leaders worked hand in hand with the self-interest of the craft as a whole, for had they been annexed by the Order they would have become subject to orders from the General Master Workman or the General Assembly of the Order.
