you think all other Manufacturing counties does not have India input?. Manufacturing is very broad term not just skilled labor on factory floor. 43,000 Indian students now in Germany. Germany stayed ahead of Japan/Korea due to integration with Europe and other labor import like from Turkey. now Germany is entering digital age. it will have more Indians. India may not need that much manufacturing consider the weather and proximity to ASEAN.
Manufacturing produces bridges and roads, not numbers on a computer. India seems to be leapfrogging over the industrial manufacturing phase straight into non-tangible assets/services phase. USA began this phase in the 1980's iirc, after a period of significant industrial growth. What it means is that India can "grow" in value in the virtual world of computer digits, but not much in the tangible world of reality.
USA went so deep in it that building basic infrastructure became a non-lucrative liability that successive governments always avoided. But USA still had a significant domestic manufacturing base as well as a currency that is the global reserve; India has neither. So, India will probably acquire the same negatives that the US faces at home in the form of declining quality of life, social unrest, etc. But even here India already has amongst the worst in the world (i.e. absurd levels of poverty, religious and ethnic violence, communal riots and pogroms).
