Demonetization is not a magical wand that will remove all the black money overnight. Now people who says it only for red middle and lower classes, know that it affected mostly people with black money in cash. Cash hoarders, Hawala money, counterfeit money and cash involved in rigging elections, help terrorism and many such illicit activities. Yes, middle class people will have to bear the pain of changing their currency but look at what it is bringing to you. And yes, it is first step, time will come and other sources of Black money will also be taken care of, matter of time, wait and watch. Even writing one such long comment takes time, let alone removing corrupt money fro a nation of 1.2 Billion where people love to ease taxes.
