Yep, when I make the argument that "the problem is resource allocation, not overpopulation" I don't mean to imply that resource availability can be instantaneously ramped up locally with an influx in population, there is obviously latency there, and there will be a lag in standard of living during a sharp population increase. But this isn't a permanent state due to there being too many people.

I don't think it is impossible to bring the projected population of India up to decent living standards, I think this is highly unlikely, but my point doesn't account for that, so it could very well be.
