Fix quotas for all communities & castes at a fixed magnitude (e.g. 20% for SC, 15% OBC, 5% Christians etc) in all sectors at national level. There should be no bias towards any caste or community in this regards. People should be allowed entry into their respective quotas only & they should get entry outside their quota. For example in educational sector, the OBC candidates should be admitted only under the OBC quotas provided for them & not through the open quota which is generally the practice. Due to this the candidates from open category suffer. If such system is under place, then automatically everything would be o.k!
