Unfortunately, ALL our political parties are hell bent on continuing reservation, though it was supposed to be eliminated after a couple of decades. They keep extending the reservation by another decade. All this means is that the scheme is flawed in logic and implementation. The richer among the backward communities are continuing to exploit the reservation (and they are influential political class too), and are not allowing the poor among them to overcome the wretched conditions they live in.
Infact it is the upwardly mobile backward castes that are exploiting the poor, as a votebank. That is the reason for them to oppose the creamy layer definition.
