Sounds like real estate to me. Even Dubai built all the side attractions, Dubai itself is a small city. I think the development would be of lesser standard than of Dubai's then.
Dubai has Industrial areas as well all hooked up with the metro and townships surrounding them. The figure amount is quite less especially when you factor in Abu Dhabi's investments as well.
In all probability with this corridor talk there will be one nice looking town built up with all the amneties and skyscrapers.
You seem to be obsessed with skyscrapers. Well they are not the scale to measure the development of an area.
And India is not Dubai. Nor in anyway it aims to become one.
May be this will help you understand:
Considering the average wage and the resulting PPP, the $90B amount to be invested in India will be of greater value than that $400B you mentioned in your previous post.
India does not intend to build skyscrapers because, unlike Dubai, India does not depend on tourism for its earnings.
Development pertains to better infrastructures, availability of basic amenities, educational institutions, diverse organizations offering diverse job opportunities, and an easily accessible market; so these are the aspects where the major part of the investment will go. Not to any skyscrapers if they are not required.
In India, if you build a market anywhere, zillions of people will come there from all corners of the country to invest their money, so it won't be long before this $90B investment ends up in building townships worth way over $300B.
Finally, India will never try to create a Dubai because already the major economic activities have been taking place in overcrowded cities like Delhi, Bangalore, Bombay etc. The main aim of this corridor is to shift such concentration of economic activities from a few major cities to the smaller unexplored towns. Building a city like Dubai would defeat the purpose.
So please understand, infrastructure does not necessarily mean skyscrapers. During the BJP rule, the govt. invested $50B (Today's prices) in building nothing but roads, famously known as the golden quadrilateral. Not a single skyscrapers was built, but these world class highways cater to over 40% of the road traffic in India.
Sorry to disappoint you man, even if you invest a trillion, you won't see no Dubai here.
