mam your anticipation is right our politicians get vote because of reservation policy. Due to that deserving people do not get reservation facility those who actually need.
Reservation based on caste status (SC&ST, BC, OBC) should be replaced by a system based on socio-economic criteria (income, wealth), so that those who need support (no matter if FC or others) can get support. This should be restricted to education. Reservation of employment should be phased out. This does not mean that I don't see that people from groups with low status should not get support, but reservation became very politicized (e.g. V.P. Singh) and also benefited those from disadvantaged groups that did fairly well.
