I had picked up these particular categories of people from both sides. Why rich people from reserved class should get these benefits whereas, poor from open category should be left to fend for themselves? In this chapter, we have not discussed the modalities of reservations but discrimination against general caste.
Somewhere you had raised the question how SC/ST/OBC part with 70-80% of the govt. jobs? There was a good percentage of OBCs who held govt. jobs prior to Mandal Commission. These OBCs maintain their ranks at par or just below the open category. When they score well, they apply in open category. If not, they apply as OBC candidates. So, approximately 15-20% of the open seats are swallowed by these type of OBCs and 5% by SC/ST/NT/VJT etc. It must be noted 50% of the seats are purely for SC/ST/OBC. So, this 50% + another 20-25% =70-75% of the govt. jobs are occupied by these categories. If you want to verify this figure physically, just visit any govt. department and collect data of all the employees.
