Have you ever seen (or heard) that any upper castes Hindu people of India does some untouchable's works/professions? Why

[Abhigyan]

No, not at all. This question should have asked to hindu priests (god's men) and prints & electronics media houses too who perhaps thinks that no one can able to understand their conspiracy and propaganda against the same human being on social ground.If this discrimination is because of the caste-system in hinduism then how can a good religion distinguish them on the caste basis.Also if all works/professions are equally important, no small or big, and if their is no such respectful or shameful work, then why they think they are not born to do some untouchable's work in the same indian society.

Where is 'Hindu Code of Ethics' ? Have you heard about that? Ethics meant for moral values, value systems for the followers.Why do they are not talking about the hindu code of ethics? They are not born for serving to others but they are born to rule the India.
