I'm not, it's just reality.
For generations caste in India has been linked to occupation. So in India if you see a barber on the street, that means his father was a barber, his grandfather was a barber, his great grandfather was a barber, etc; what this leads to over hundreds and hundreds of years is people who are extremely good at what they do to the point where it becomes almost second nature. So the Patels in this example honed their farming and agriculture skills and use their tight knitted nature as a community to their advantage and became socially dominant, regardless of their caste. These are the guys you see who own businesses - pizzerias, subways, convenience stores, gas stations, 99 cent stores etc...Punjabis are similar. A lot of the children of these people usually have no interest in continuing the family business so they go to school and become doctors, engineers, etc....
In the case of Brahmins, though never materially wealthy, their occupation according to caste has always revolved around teaching (guru) and religious/spiritual matters. Since education in India has always been linked to religion (unlike the west), Brahmins have cultivated a culture where learning and knowledge are stressed from birth. So this is why the greater majority of these Indian guys you see on silicon valley. scientists, academics, tech professionals are all Brahmins. Since they are an extreme minority in India, many of them left because they realized that they could use their intelligence to get rich in the west. In India this has been criticized as a "brain drain." So in a sense the people who say : "oh well those Indians who come here are already ahead of the game" do have a point, but it's a lot more complicated than just being well off right off the boat, because not all of them are. It has much more to do with the culture.
