Honestly the more such help is given the less efficient the already inefficient govt will become.i would rather ambani spend his nillions in the next disruptor like a Jio and create 10000s of quality jobs. The govt will only be too happy to let him do that and pocket what they have to.
Secondly - it's just media speak on Ambanis billion dollar home. It's not just a home, it also doubles up as convention centres, place to receive clients etc. Allnin all a home office where he doesn't have to spend other things. So it just catches eyeballs if you day he has a billion dollar home but the reality is something else.
