Then all the functionaries on paper appear to be brought under the control of the people.
Now the system in all other areas is that any official has to rpeort to the people's representative of that particular locality/area and if any public servant delays in meeting and reporting the local leader about his posting, when he joined etc., it sends a message that he is head strong and is not caring the local leader and all the henchmen of the leader start creating hudles/probnlems in discharge of their duties.
Instead of rserving certain seats etc., the Govt. should make a roaster of all such aspirants in the OBS and fill all the seats with them. Even Govt. can send all such people abroad at the Govt. expense and equip them with additional qulaifications in at PG level.
