good point and true for the most part but it's still rampant in rural India, hopefully that diminishes with development and economic empowerment but even among the "elite", while it might be mostly relevant and practiced wrt marriage, some do cling on very tightly to the perceived prestige, and from what I've seen, tam-brams are the worst, I've been told off as a lower level brahmin myself
, but that was among friends having a beer, but it's telling of how we're all structured, it should be gone by the next generation.
