the great Indian humiliation also known as Demonetisation

in Nov 2016 the Govt of India demonetised, i.e. made certain currency notes useless with a notice of 7 weeks. In India more than 97% of daily transactions happen in cash. The scheme was supposed to flush out 'black money' i.e. illegal currency out of the coffers of smugglers, builders, etc. It was ineffective as the big operators don't stock cash , they invest overseas in dollars, in s - real estate. Instead it affected the poor the most. For 7 weeks the country was in queues outside banks, post offices to deposit their cash when many of them have never seen inside of a bank.  And did never need to. It made everybody feel like a criminal.
