Calling Modi government 's demonetisation as the biggest scam of the year, former finance minister P Chidambaram asked for a thorough probe into the move.Terming it as an absurd and thoughtless move, Chidambaram questioned the effectiveness of the action in the wake of the recent cash seizures.Here are 10 key points on the cash ban he raised:1) Goal post is shifting, it is no longer about black money , now they (Modi government) have found a new one called cashless economy.2) I cannot get a Rs 2,000 note. How did tax department get crores of Rs 2000 notes in raids all over the country?3) Every bank says there is no cash. So how does the government say there is enough cash?4) It is like motherhood & apple pie. No one speaks against them, similarly no one will speak against cashless society5) Even a natural calamity migh not cause so much trouble as demonetisation6) Debate in Lok Sabha without PM is like Hamlet without the Prince of Denmark7) Which country has cashless economy? Does US, Singapore have it? Where is electricity in country? Where are the machines?:8) Modi should have consulted at least Yashwant Sinha, he is their own man9) Won't be surprised if government withdraws Rs 2000 notes soon10) To assume that India will go from 3% to 100% cashless in a matter of few months is a outlandish expectations
