It is better to keep away the govt. from procure store and distribute food items and instead pay by cash to the card holders what amount govt. intent to subsidise per head for PDS commodities. Peoples can buy good commodties as per their choice from open market using this food subsidy distribute by gov as cash.
Then the corruption will not occure and also gov. can save lot of administration expenses for procure, store, distribute and also loss of grains during transist.
But this will not allow as corruption not possible for all sectors behind this system ( from sales man to ministers)
