Mumbai has been developed as the financial capital of India, by the central goverment. All the important financial institutions were set up there.Therefore, the headquarters of almost every Retail and investment banks are in mumbai. And also corporate headquarters of many companies... This all has been achieved by using taxpayer's money.. from all over India. Now the Mumbai has become a major city by using resources from all over India.. It is completely unjustified to claim it, by any single group. Violence only begets more violence.. It has been never a solution...and It will never be.
