This is Group psychology, sense of entitlement, and social bullying gone to unhealthy extremes, since childhood like sits with likes in school, cliques exist with in workplace environments, corrupt breed more corrupt freinds, Unfortunately there is no law against such discrimination. its not JUST the underprivileged, social, ethnic, sectarian and class discrimination exists among all sections of the society at all times of history, wherever this crass notion of superiority versus the other’s ‘inferiority’ exists its wrong, individual acts of kindness and fairness can make a big diffrence.
Karachi on principal shd be made a separate province regardless of this discrimination. Unfortunately there is no law against quota & domicile system in pakistan & social, ethnic, sectarian and class favoritism seeping into public life & and work ethics exists among all sections of the society in pakistan!!
