The impact on common man is huge, It may be a short term as the common man is expecting this issue to be resolved in a month or so ...... Inspite of the hardships there is hardly any opposition for this move, do not forget every Indian is facing hardship....The reason is simple, common men doesnt suspect the intention behind this move.....The salaried class is not affected in any way as their money is safe in banks, but look at other sections as traders and business class, all of them have been hit big time, and they have no clue when their business will be back on track..... I would say lot of thought has been put in to before taking this move, Yes it could have been better..... But If the secrecy was key, then there is hardly anything more one can do.....
