Mumbai for ALL, But No One for Mumbai

Mumbai belongs to everybody? Really, or is it that everybody wants to belong to Mumbai?
Experts of all hues say that the constitution bestows a right to seek employment anywhere in India. But most importantly the constitution is mum on dignity of a citizen. Shouldn't the right to live with dignity be of paramount importance.For long Mumbai has been the land of dreams and opportunity. A significant chunk of India is spread across the failed states of central and northern India. Millions from these states flock to Mumbai every year. They slog hard and lead a piece meal existence. In a way they are like birds who fly to warmer climates in winter. But unlike the birds they cannot get back. Millions of such birds keep flocking to Mumbai every year. But the truth is the warmer lands are harsher than the cold climates.
Mumbai has become unsustainable. There has to be some kind of censorship to control its inorganic growth. I dont condone the sena, I care for Mumbai.
But I would like to put a question to all the Non-Mumbai intellectual crowd who proudly say Mumbai belongs to all. How many would agree for a National tax for Mumbai. It pinches right? If Mumbai belongs to everybody, everybody in India has to contribute for it. A healthy Mumbai is necessary for a healthy India
