The old adage come to my mind - The wolf cries that the sheep is drenching in rain. Here is another wolf that cries about caste inequality.
If casteism is stopping us from becoming a super power, then is 'Iyengar' a honorary doctorate conferred on you by a foreign universtity? What a joke!
Caste doesn't go away by preaching to others, but by individuals shunning their castes. It won't even go away by not using caste names, because casteism is only a mental disease. If ever you are really serious about abolishing caste, it will happen by creating a new generation of Indians, who would not be able to say to which caste they belong to. Inter caste marriages are the only solution. So, when your son or daughter reaches marriage age, make it a thumb rule, to seek alliance only from outside your caste. I am not suggesting to go down right to the bottom of the society. There are prosperous candidates in other castes, equal or better than you, in educational and economical status.
If this suggestion does not appeal to you, then we go back to the adage - The wolf cries...
