Ghost of a flea

R. Parameswaran has suffered that reversal of fortune. The 29-year-old starts every day with a prayer to the Hindu god Shiva, marking his forehead with red and white powder to let the world know he is a Brahmin. In his home village, his caste's mark brought him respect, but since he moved to Chennai, a sprawling high-tech city in the southern state of Tamil Nadu, in the late 1990s, he has found his status a liability.

In Tamil Nadu, nearly 70% of government jobs and public-college slots are reserved for people from lower castes and other historically disadvantaged groups. Although he says he graduated near the top of his high-school class and had strong test scores, Mr. Parameswaran couldn't get into any of the state engineering colleges. His family had to borrow from friends to send him to a second-rate private college.

He now teaches English at a small vocational school. On a salary of $100 a month, Mr. Parameswaran can't afford an apartment, so he sleeps in the classroom at night. "I am suffering," says the intense young man, using the exaggerated enunciation of an English teacher. "Unfortunately, I was born as a Brahmin."
