One nation one tax not in true sense

In one nation one tax - GST - various taxes are combined into one is a good measure but its originality as in most other countries is spoiled due to Central and state governments differences. Moreover, Aadhaar concept is good but not by force and making it mandatory for almost at all steps in life is not in public welfare especially under Indian conditions of life. Its use for criminals only is justified. Passport is enough - in broader sense - Aadhaar is duplication of Passport which has much wider application in day-to-day life.
