I haven't read through the posts but no..reservation shouldn't be ABOLISHED.
One should understand the basic tenets of our constitution. The idea behind having reservation was to bring the underprivileged into the mainstream development. The idea was equity in growth and development. Benefits of development barely touch some sections or pockets of our society.
There are still people(people from these same caste could be benefitting from the policy, there are two ends of a spectrum in our country, we shouldn't be blind to it) communities in the fringes of our society that are still incapable of availing the basic amenities. These people need help, support because of their backwardness(eg. Tribal communities) ..even if an originally backward family are able to get their child to school, there are cases where child cannot study due to lack of electricity, conveyance issues etc.
One should understand the problems deeply entrenched in our highly complex and heterogeneous Indian landscape. It really takes generations to move along with the mainstream Indian growth, unless one generation sees skyrocketting growth in their quality of life owing to a life-changing career.
Yes, there are people gaining undue benefits owing to their caste.
Hence, reservation policy has to be revised, revamped, rationalized by taking into account the economic position of the family rather than their caste. Annual income should be taken into consideration along with the educational qualifications of the said bread-winner(s) [so as to rule out discrepancies] .
But doing away with this policy is sure to leave certain people behind which can be disastrous for the nation as a whole, not only those families.
