Traditional Indian "Joint" Families: Are they quite the paragon of support?

In a recent post, noted Indian educationist and social commentator Meeta Sengupta has wistfully (as she herself noted) sung paeans to the traditional Indian family, also referred to as a "joint-family". Do read the eloquent essay in her blog, and I encourage you, dear reader, to interact with her. Understanding her point of view is important for another reason, too: it'd help clarify my position on this - in sharp contrast to hers. This is a matter of some significance to me, and hence I chose to respond via a blog post of my own. I think a disclaimer is important here: I greatly admire the wisdom and thoughts of Ms. Sengupta on different aspects of education, and we follow each other on Twitter. Rarely do I have an/any occasion to disagree with what she writes; however, this essay of hers seems one of those rare occasions, where I disagree with her thesis. This response is not to engender acrimony between us, but to present a viewpoint that is - as will be apparent - patently different from hers in this matter.
