Funny -- I had never heard of the "Teacher" caste before. But by the same measure of anecdotal evidence, there must exist a "Hollywood caste” in US -- how else would you explain Will Smith's kids going into entertainment biz. Or may be there is a Pizza maker caste -- what else could explain the family owned pizzeria next door. My daughter's paediatrician is my doctor's son and he is married to nurse. There must be a doctor caste to explain this.
