The key to Modi's success and India's success is bringing in the unaccountable economy into the official economy.
For most developing nations this could be anything from 20--50% of the real PPP GDP.
So if the Indian PPP GDP is $5.5 trillion.....then perhaps as much as $1.8 trillion of the Indian economy operates in the unofficial sector.
One of the reasons why the Mughal Akbar was so successful was his efficient tax system, and the ability to accurate assess peoples income.......and then spend it on infrastructure.
Part of that project is tracking the unaccountable money in the 70 odd tax havens around the world, and then there after discouraging Indian's from following the practice.
