Demonetization has both positive and negative impacts that differ depending on perspective. Positively, it aims to curb black money, fake currency, terrorism, and corruption. However, critics argue it was poorly planned and implemented, causing significant short-term hardship by limiting cash and slowing the economy as people and businesses adapted. In the long run, supporters believe demonetization will formalize the economy and boost tax revenue, outweighing short-term costs, while critics doubt its ability to achieve goals like reducing corruption.
