At age 21, [Nisha] Mehta has five people -- all older than she is -- working under her. And her boss says the sky's the limit. This is a seismic change in a country where women have, until recently, been restricted to traditional family roles. And it's a change that has transpired within one generation in one household. Mehta's mother never went to college, doesn't work and cannot make major decisions without the consent of her husband. Mehta says she has no desire to live the way her mother does -- and her mother has actively encouraged her not to follow in her footsteps. Mehta is conducting an interesting -- and seemingly effortless -- balancing act between two very different worlds. On the one hand, she lives at home, as most unmarried Indians do, in a tiny, two-room apartment. She shares a pull-out couch with her little brother. On the other, she is financially independent and also insistent that she will not submit to an arranged marriage, as the vast majority of young Indians do. Mehta says she wants a love match." But, she says that she'll get her parents' consent before marrying and that she won't marry anyone from outside her community. The changes going on in India right now -- the breaking down of old barriers of gender, religion and caste -- are incredibly exciting. But it's important to realize that these changes -- as of right now, at least -- are only affecting a minority. India's exploding middle class is estimated to be 300 million people -- roughly the size of the U.S. population! -- But there are still 600 million people living on less than $2 a day.
