A legendary and remarkable Demonetisation step taken by PM.
In India people feel proud / achievement evading tax and still criticise government for infra structure etc. Tax contribution is necessary for healthy nation. This will bring in more people under taxation system and will help reduce burden on the current tax payers.
Huge blocks of money/cash lying stagnant in lockers can neither contribute to Industrial growth or job creation or Nation building - so it was necessary to pull that money into banking system for proper utilization in future.
Opposition is shouting because they have become handicapped and are not even able to create Nationwide disturbance / violence because all their black money has become plain paper and they are now unable to fund anti-social elements to carry out actions to show that public is against the move.
Well played Modi ! Ek teer se kai nishane laga diye. (A few to mention are Terrorism, Naxalites, Tax evaders, Black Money, Election expenses, Fake currency, Loan outstanding settlement with old currency, Municipal tax recovery with old currency etc.)
It has also exposed political leaders who sang the song of anti corruption since years and are now crying when the time has come.
Nothing comes easy in life - so majority of us stand with the Government's Demonetisation decision.
As far as Real Estate is concerned I believe that that market will improve as the salaried persons cannot afford to buy property if they have to pay Black Money - but will be able to buy if the total amount is to be paid in white (Because they can avail loan and pay EMI if the total amount is white).
