Dear Shri Sravna,
Both the points contained in the above post, are, not factual, imo.
That "the brahmins have something that is different and more importantly something useful to offer to others." is a myth. Brahmins or the brAhmaNa varna somehow came to be regarded as the "highest class or group of people" in a certain social set-up. They also became, by force of circumstances, the "intermediaries" between a godhead which was more perceived to lie outside of the living devotee, rather than being within that devotee himself (I am knowingly omitting the 'herself' part, because the brAhmaNa religion did not look upon woman as anything more than a chattel of the male.).
Having thus become the crux of the society, somehow, all the efforts of the brAhmaNas have been, historically, to secrete whatever knowledge they had and not to disseminate it. Such an effort can be justified because historically, the brAhmaNas (at least the vast majority of them) had no other skill except, the knowledge and the use of the scriptures to pose themselves as intermediaried between Man and his (foolishly imagined) external god.
For the last two centuries or so, most brAhmaNas have virtually dissociated themselves from learning those scriptures, understanding those and using such skill and knowledge to eke out a living as intermediaries between Man & god. The "brahmins" today, are mostly an "advantaged" labour class (not withstanding the usual grumblings about the reservation system) which will move anywhere where there is a chance to make more money and live a life full of maximum materialistic comforts.
Hence, such a brahmin class has nothing unique left with itself, which can be offered to others as useful.
By the same token, the tambrahm or the extended brahmin class in India does not any longer represent anything spiritual, other than the bottled variety which is favoured even by some temple priests and vaadhyars, etc., not to speak of the ordinary brahmins. The good thing today is that our scriptures and the secret knowledge of brahmins is no longer secret and can be accessed by any one anywhere in the world.
