I am repeating again... When Tata/Birlas buy steel they legally pay taxes and royalties to the Centre and Jharkhand state. So there goes your argument that taxes paid from Mumbai are not from Mumbai.
Regards your market from the North, it is a free market with companies fiercely competing for selling their products and the North customer has the right to choose the product as per their wishes. They choose Tata/Birla because these cos bring out the most cost efficient and quality product which makes it a best buy product. Thus it is the entrepreneur who does all the hard work of getting labour and capital together creating and selling of a quality product leading to corporate profit. It is this corporate profit of entrepreneurs which is getting taxed by the Centre that I am referring to.
It is more than 60 years since the British left India and Mumbai has continued to remain one of the most favourable cities for conducting business. It is deteriorating now since the Centre is unfairly not supporting Mumbai's infrastructure which is bringing down Mumbai.
