Isn't this the exact moral qunadry that the author faces right now? India (and China) benefits from what I call as human subsidy. The living standard on average for general population are low which lead to reduction in cost for manpower, which makes stuff cheap. Sure if you are in top 10-20% of the earners, your life is amazing, you can have all the benefits of developed world at the price of developing world. I am not saying that people who live in other place are free of such guilt, consider Americans buying Apple products, made by Chinese workers who live in poverty. However for Indians the guilt is significantly higher. At least Americans can invoke Us vs Them argument, or point out the fact that actually buying the products might be the best thing that they can currently do considering their government.
Regarding India,there would be significant inflation in next decade, the main problem will start when our generation enters later thirties. There would be significant stress on India's healthcare system. (Indians might make fun of US healthcare, but Medicare/Medicaid is amazing and there is no equivalent in developing world). Worse India does not even has large army or pressure to grantee energy security. Unless there are groundbreaking inventions in energy/healthcare (which are quite possible) the next two decades are going to be challenging. India's best bet is that its demographic dividend and ageing population in US/Europe, pays out.
