Strain Theory, old and not without limitations, but still relevant.
“... actual advance toward desired success-symbols through conventional channels is, despite our persisting open-class ideology, relatively rare and difficult for those handicapped by little formal education and few economic resources. The dominant pressure of group standards of success is, therefore, on the gradual attenuation of legitimate, but by and large ineffective, strivings and the increasing use of illegitimate, but more or less effective, expedients of vice and crime. The cultural demands made on persons in this situation are incompatible. On the one hand, they are asked to orient their conduct toward the prospect of accumulating wealth and on the other, they are largely denied effective opportunities to do so institutionally. The consequences of such structural inconsistency are psycho-pathological personality, and/or antisocial conduct, and/or revolutionary activities. The equilibrium between culturally designated means and ends becomes highly unstable with the progressive emphasis on attaining the prestige-laden ends by any means whatsoever. Within this context, Capone represents the triumph of amoral intelligence over morally prescribed "failure," when the channels of vertical mobility are closed or narrowed in a society which places a high premium on economic affluence and social ascent for all its members. This last qualification is of primary importance. [...] It is only when a system of cultural values extols, virtually above all else, certain common symbols of success for the population at large while its social structure rigorously restricts or completely eliminates access to approved modes of acquiring these symbols for a considerable part of the same population, that antisocial behavior ensues on a considerable scale. In other words, our egalitarian ideology denies by implication the existence of noncompeting groups and individuals in the pursuit of pecuniary success. The same body of success-symbols is held to be desirable for all. These goals are held to transcend class lines, not to be bounded by them, yet the actual social organization is such that there exist class differentials in the accessibility of these common success-symbols.” (Merton, 1938: 679-80, emphasis as original)
