Urban migration collapses lineage hierarchy into undifferentiated conceptual brotherhood.

Evidence

Away from home the migrants abjured any simulation of this religion of descent. Genealogical differences of generation were collapsed into a single conceptual brotherhood; ancestor worship could not be practised since the structure of home groups necessary to make up a Sacrificial congregation could never be replicated. The sheer unequal power of parenthood writ large was mainly absent in the slums, where ethnic solidarity found expression in beer talk and kinship was a domestic relationship of uncertain moral provenance. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 2309
