I do not understand the relationship between caste system and reservation in govt. jobs. If somebody ill-treats somebody on the basis of caste, it should be made a punishable offence. He should be punished according to law. But why reservation in jobs ?
It is surprising that people from so called backward castes are still not accepting the exhortions to avail all the educational benefits from govt. and compete in general category. Perhaps they have become used to charity and do not want the charity to go away. Initially the framers of constitution had kept the provision for 10 years based on need, but now it has turned into greed.
It is also saddening to see these people referring to themselves as people from lower castes repeatedly. There are different castes. Why some self respecting person should tell himself that I am from a lower caste ?
