Biharis - Migrants or infiltrants?

Some times in lighter mood I think like this. In fact in written history of India, it was Mauryas from Bihar who established Indian empire rather that empire was larger than the present India. It was Sher-shah Suri from Bihar who gave the key of peacefull and integrated ruling on which Akbar came up with the best mougal emperor tag! After that India has been existing only geographicaly. Politicaly it could be united only by britishers. After independence, different states marched forward to industrialisation getting support of the "BABUS" of Bihar and UP. But integration of the states in Indian Nation remained incomplete! Biharis have taken up the responsibility as usual - the job which was started by their forefathers need to be completed by them only! Who else can do that? Bihari labourers and other workers are just ambassadors of the Indian Nation. People in other states have to learn to live with them. Only then Integration of India will be complete. Basicaly people from Bihar and UP are not just migrant labourers, they are infiltrants of the Indian army's cultural wing! Recent study has shown that the migrants who are in many areas of the country being termed as Biharis, are basicaly not exactly from the geographical region of Bihar, many of them are from UP, Madhya Pradesh and Orissa. So Biharis are not just "VIHARIS" they are the infiltrating "REAL INDIANS".
