I've spent a lot of time in various parts of India backpacking around in the past. No luxury bubble somewhere on beach of Goa, rather travelling around cramped public transport, sleeping in cheap or free places, interacting only with commoners.
Everybody and everything is growing, even North Korea in some aspects is. Thats called a progress and nobody interacting with rest of the world can escape that.
What is unfortunately true about India, and many other similar places is the potential of the country and the people and reality where they got and how far they can reach, given their own limitations.
From what I've seen, the gap (potential vs reality) is huge compared to western standards, and I don't see an easy way to push through that ceiling. Society isn't fair, its everybody for themselves. Castes are very much a thing still, absolutely horrible and deplorable thing (while this will be read mostly by brahmins or rich merchant castes who rarely see an issue there, so I don't expect much sympathy here). Corruption is abysmal. Women and minority rights are questionable at best.
No doubt great and important things will improve in upcoming decades. But in 21st century India will not resemble ie western Europe in any meaningful way, I just don't see a way. Real India is not some Bangalore or Pune bubble, its very opposite of it.
