Already it's more than 5 years since construction began. It might take two more years to fully complete. At this speed it will be hard compete with other established and emerging manufacturing nations. If this attitude towards infrastructure continues India might lose the chance of developing till 2047 wasting it's current potential of demographic dividend.
Don't go by Jumlas of being a developed Country. 25 yrs is nothing if not backed by serious work on ground on all parameters not only on road building but railway, airport, school, colleges, health,. Hospital, medical Centres. We are wayyy behind.
We are way behind due to ur chamcha and katua politics. Land acquisition takes time because it cannot be forcibly taken from farmers, hence the delay. 2047 may seem little early but Bharat is surely on track to be a developed nation. During Ur 60 years of govt, only a few families were being developed. You incorporated corruption in our culture which is so difficult to uproot now. Compare ur 60 with our 10 - u would know what am I talking about.
