Economics of Rupee :
Govt(RBI) prints currency notes based on value of Gold it possesses.
If rupee is weak against international currencies Govt take all Gold lying unused in Temples... and also Fix limit to possess Gold by a single individual.
The hidden unaccounted Gold can empower Govt to become stronger in International Monetary circle and get Better Credit. That will 'attract Foreign Investors...
more... and Entrepreneurs to invest and make in India project of Govt.
So after demonetization, govt may start controlling 'Gold' or 'benami properties'
Govt itself is a Big Entrepreneur who is creating Wealth in India....
