The golden age of hindu rashtra was built by the sweat and blood and Slave labour of Dalits and other lower castes for nothing in return, not even recognition.

Their life was so cheap that a Brahmin could kill a dalit for no reason without repercussions. Even if a Brahmin committed mass murder the worst punishment they could get is to get their ponytail shaved.

Women also had no existence without men because of Sati.

This dichotomy existed at least since the Mauryan Dynasty as far as Archeological evidence goes that's around 327 BC
