I am an Indian and I echo your sentiments. Federalism, which was supposed to work really well, is failing at all levels in our country. A single vision to move forward does not germinate and even if it does in one person's mind, it is impossible for that vision to see light of the day. Even a flagship project like the bullet train is unable to take off because of corruption at the grass root level (panchayaths and the like).
In India, a vast majority of the population doesn't realize the growth by letting others grow concept. The predominant sentiment is to grow at someone else's expense, meaning I have to grow and others shouldn't or even if they did they have to grow less than me. This manifests in every step and walk of life. This leads to all sorts of corruption. Some guy who owns a key piece of land won't sell that land for a public project, just because a politician who doesn't want that project to succeed will back him up and prevent him from selling. This happened in Bangalore when a key arterial road was being developed. As soon as word got out, some local politician flooded a key government land with slum dwellers and overnight they occupied that land and prevented the road construction. Stories like this are the norm in any land acquisition.
Of course there are exceptions, and that's how this country is seeing modest growths of 6-8%. I say modest because, our baseline is fairly low, as compared to other economies. I feel so bad, we have the highest inhabitable land mass of any country, some of the most fertile regions, no adverse weather in most parts, bio-diversity to die for. It's like someone handed this climate on a platter, yet we don't realize that. We are just destroying this paradise day by day.
