No there is nothing casteism about it. Have been listening a lot about the immigration reforms and some of the comments made by the senators and other influencial people of the society. It seems time and again it has been said that the US need migrant workers for the work Americans do not want to do. That struck the cord. Is that something how centuries ago a caste system was introduced in India? The division of labor and the emergence of a labor class? The labor class later being increasingly alienated and ended up changing the political equations. I do not like "classes". The empires which spread it were doomed and I hope it does not come back in the free world again.
