On November 1, 38-year-old Ravi Kumar Sahu spent his life savings from 20 years of working to invest in a leggings business in New Delhi. His joy of starting his own business was short-lived, as a week later Prime Minister Narendra Modi announced the ban on 500 and 1,000 rupee notes and his orders dried up. Now, he and his family have to borrow money to survive.
