YES. Chandragupt was a dalit, A brahmin Chankya made him the Supreme King of Bharat Varsha. There was no opposition to him from any Brahmin in Takshshilla. As a matter of fact Brahmins were his solders in initial fights. If Non Brahmins, and those who are called Dalit in particular, were not considered Hindus then they would have converted to Islam or Xianity. But they did not. It means there was some Vyavastha for them too.
Current Education System in India was brought by British people after 1836. There were no schools of this kind. The education before this kind, was only about Dharma and nothing else. Brahmins were enthrusted with the job of preserving the literature which was so precious. And that is why they were not allowed to mingle with others, so that they do not stray. Think about the isolation they must have gone through. If you ahve read the history of India then Brahmins were always beggers before budhdha and muslims. I have seen brahmins begging in my own town as late as 1980s.
