Buss, why are you getting so worked up about China? Chill, okay, China will be China, India will be India, each will grow or decline according to their own pace. GDP is just a number, wealth is not just about accumulating dollars, it is about improving lives, like HSR, water treatment plant, less pollution, green energy, electric cars, metros, education, more efficient food and material production and R&D, etc. A large portion of US GDP is in wall street casino, and a large part of Indian gdp is tied to servicing this casino. In the end, real tangible goods and services matter, not 'financial services' which does nothing but push credit around. India might be the top 5 largest economy but what is the use when you have the most polluted cities on earth, that without even the Chinese level of industrialization, when people starve, when the infrastructure is like Africa and dirty streets with poos water everywhere. There is no point being a supa powa like tht, it would just be a Republic of Poo.
The Indian Rupee is highly dependent on investment inflows to keep it's value, otherwise it is basically toilet paper. China does not allow liberal investment within our financial markets due to independence and security reasons. Therefore a large portion of forex is from trade. The rupee used to be 45:1 now it is around 64"1, China used to be 8.2:1 and now it is 6.5:1. In actual fact, China is trying to keep it normal, not too high and not too low, we are an export oriented economy afterall.
