It is now slowly accepted (though known all along) that caste is not a bane, but a useful and welcome social and cultural capital if not misused by divisive politics and vindictive social behaviour. All jatis have lived together in conducive harmony in every village and town. It will be far easier to remove inequalities in education, skills and wealth, than blaming jatis and vowing to destroy jatis. It will never happen. Use of brahmin bogey to solve dalit problems has lost its steam; dalits have seen the deception, but some brahmins (so called) still cling to the rejected theories.
In my school in early sixties, out of 8 sections of 45 students in each, in SSLC, only one and a half had brahmin students (65) studying samskrit as third language. Remaining 300 students were not brahmin and had selected advance tamil. There was no discussion or awareness of dalit/sc/st among the students and there was no visible discrimination. The english brought the caste divide and the modern secular politicians have amplified it and made it a explosive issue.
Dharampal has shown from documents available during british raj, in madras presidency, less than 20% of the students in schools were brahmins; the rest from all the three varnas (they used the k-v-s classification). And every village had a school.
Modi has the right catch phrase - sabka sath, sabka vikas. He is a modern hindu who respects all jatis and adivasis and does not believe in setting one against the other.
