Yes but the cities named by you, discretely follow the son of the soil policies! Imagine yourself comeing to Mumbai and no one communicating to you except in Marathi! That is exactly what happens to a guy coming to Chennai! So dont shy away, lets call spade a spade! The statistics of employment opportunities vs son of the soil employed in those vacancies speak for themselves. Can I request you to declare the list of new recruits at Chennai railways and show me the % gone to people other than tamils?
