I don't agree that North Indians are spreading. IN Delhi, my uncle employed Kerala typist because they were ready to work hard for less. Delhi girls used to come for jobs but never protested that these dark keralites can do it because 5 of them live in a room. Some of Delhi girls were not rich. Yet I never saw massive unity and protest as you see in some places. SO WHY IS SUCH HOOPLAH in Maharastra.
