Lewis Coser perennially discussed various forms and facets of ‘greedy institutions’ with their total grasp on the individual. Coser’s ‘greedy institutions’ demand undivided time and loyalty from the individual who will voluntarily devote him/herself for exclusive benefits only granted to loyal followers. Although the ancient authorities have vanished—princes with their court Jews, masters with their servants, or religious and political missionaries— one can argue that the idea of the greedy institution is far from obsolete today. Management consultants, 24/7 old-age carers from Eastern Europe and particularly the ‘hive mind’ of new social media show that a revisiting of Coser’s theory can help in understanding modern forms of greed in institutions. This awareness may enhance vigilance against intrusions into personal autonomy.
