Well Said. Totally agree with you. Not only Mumbai. Add Chennai (with 100 km radius), Calcutta (with 100 km radius), Bangalore and Hyderabad and other big cities should be declared as national business centers, governed by President (not even the corrupt MPs) or by his IAS officers. Ther will be elections for these officers only. English, Hindi will be must in Education plus the local language. India will be very different in a few years.
