Vice President M Venkaiah Naidu has said India can not be developed if there are glaring inequalities based on caste, creed, religion and sex. Mr Naidu said, the evil of caste people have inherited casts a shadow on the rich culture. <br/><br/>Addressing the gathering after releasing the Book Social Exclusion and Justice in India authored by PS Krishnan in new Delhi yesterday, he said, it is a blot on the universal, humanistic philosophy India have espoused. <br/><br/>The Vice president said people must as a nation take the resolve to implement the constitutional provisions pertaining to SCs and STs and should get inspired by the noble thoughts from the past, commit themselves to the letter and spirit of the Constitution. <br/><br/>Mr Naidu said, there should be a national debate on sub-categorisation of Social groups to reach the un-reached. <br/>'''''''<br/>
