Politicians hate to accept mistakes / policy errors. It's no surprise that Modi doesn't want to say out loud that the note ban did not go as he had hoped; some positives, but not worth all the trouble, and he'd probably have abandoned the exercise had he known the outcome, but he isn't going to say that. Perhaps a lot of people expected him to be a better statesman and feel let down. Anyway, time to move on and clean up the balance sheets of banks before the next recession that many are predicting hits.
