For our purposes, these situations exhibit two salient features.  First, incentives for success are provided by the established values of the culture and second, the avenues available for moving toward this goal are largely limited by the class structure of those of deviant behavior.  It is the combination of the cultural emphasis and the social structure which produces intense pressure for deviation.  Recourse to legitimate channels for “getting in the money” is limited by a class structure which is not fully open at each level to men of good capacity.  Despite our persisting open-class-ideology, advance toward the success-goal is relatively rare and notably difficult for those armed with little formal education and few economic resources.  The dominant pressure leads toward the gradual attenuation of legitimate, but by and large ineffectual, strivings and the increasing use of illegitimate, but more or less effective, expedients (1968, pp. 199-200).
