Why do some people try to denigrate something which is wonderful with smart alecky comments.
Now back in 1960 I can only imagine the chaos the country was in. We just got independence. State and central govts are just figuring out, how to run a country. How to channel funds where the need is most. There is whole bureaucratic and panchayat system which is still being established. Also a state funeral after 47 years hardly can mean anything other than the deed was well done.
Having said all of above, Bihar is still a poor state. Current state govt. is trying but I wouldn't be surprised if similar things happen again. It is not very unusual for entire river bridges to be washed away during some rain and villages to be cut off from rest of the world (even now).
I'm reminded of a more modern context in the shape of the Craigslist/Padmapper debate, one guy may have built a new Craigslist right now and is out there signing up people one or two at a time to post on it, and in 20 years that person may carve a new path into classified listings. But who really thinks about embarking on tech projects these days which might take 20 years?
