It's a shame India's still being held back by its primitive caste system. It's hard to imagine it will escape from its third world status if it clings on to outdated prejudices.
Perhaps you will empty that sawdust in your skull and learn to research something before pontificating on it as if you understood an iota of it.
First fact: you are an untouchable.
Second fact: independent India, that is, India after 1947, instituted many reforms that were in motion far before its independence into its constitution. Caste-based discrimination is outlawed yet people from all over India cling to their "castes" in order to benefit from the 'reservation system' which "reserves" seats (or places) in colleges and government jobs for the so-called 'lower castes'. This system, which makes the "affirmative action" look like a circus, is what has actually kept India economically in shambles. If it was a purely meritocratic system, as it was for thousands of years in India, India would be what India was; the "crown jewel" of the world and the richest nation on this planet (until the 1830s).
Caste based problems are dime a dozen in India because it is beneficial for politicians to use it as leverage to get elected; one caste is favored over another.
Western nations go to great lengths to hide their atrocities and have the temerity to talk down to Asian nations and especially India.
England has been robbing other countries in Asia and Africa for centuries and made themselves wealthy and now, after utterly destroying many Asian/African economies, cultures, and peoples, have the audacity to call them "poor".
The funny thing is, so-called "high" caste people are denied jobs, entrance to good schools simply based on their caste. That is why so many 'high' caste Indians emigrated to the US, UK, and Australia in the 1960s and 1970s. In a meritocratic society, Indians dominate. In fact, Indians are the richest and most educated minority in the US (

You know nothing about caste and so it is better you don't comment on it. When you think you want to comment on it, just refer to the first fact I wrote here.
And, caste has nothing whatsoever to do with skin color or any superficial characteristics.
