Bhaiya / N. Indian / SCs / Muslims.. are all words used by rich people to supress poor people. I am here in US and here also people use the same language. The words used here are Mexicans, Immigrants. In Europe they are eastern european and Immigrants. Ironically the NRI marathis running their mouth here do a 180 when they discuss the issue of immigration to US and UK. But to summarize it seems like a human nature to climb up the food chain and kick on the down and out.
