This is a possibility and as per Murphy’s law (what ever can happen will happen) that in a near future the people who claim to be of a higher caste in India will be ashamed of being of higher caste and their children will pray to God to be born in an SC or ST family.
You can refer below link of Dainik Jagran and find how high caste people made certificates of being an untouchable and got their degree from DU.
Thanks to the OBC, SC ST Leaders in Indian politics. Today an untouchable has more value than a higher caste person.
India should also launch a certificate of High cast because if high caste can become low cast there should be a certificate which changes a low caste to high caste.
