for your information nothing has been given to tata for free. the land, electricity, water etc. please check up the facts before posting messages here.
creating employment is not the job of the industrialist. they are ultimately responsible to their stake holders. have some knowledge about what is induatry and business. it seems you are expecting tata to assume the role of a government!
