This is the Indian demographic dividend that is going power the nation forward for the next couple of decades. So the potential for India to threaten China's own workforce is delusional for the foreseeable future.India might not be as competent as China (and may never be), but by sheer demographic heft & the BJP’s grip on power, it will inevitably have to be contended with. China needs a “India strategy” in the same way the West needed a “China strategy,” the only difference is that China has the benefit of hind sight, and can avoid making the mistakes the West did like out sourcing its entire industrial base & letting in so many immigrants their societies are now fighting amongst themselves.
China is not run by liberal nut jobs. There is no chance they are letting young men like these to so easily immigrate into China. These young men can't even grow their own country, so why should China's cold realist government accept people like these?
