Rajeev is right in highlighting that the caste system is simply group identity, which benifits the political class for manipulation. The communists who preach non caste based system are vehemently backing OBC reservations. Thier children are practioners of capitalism ( jyoti Basu's son is a Indusstrialist). Mayawati's victory should not be read as any socialogical realignment- she would be back with her "manuwadi" speaches and Ambedkar statues business. It is sad to see that BJP is not able to solve its internal squables and come out with a good winning team.
