It's no doubt that Aadhar was a blatant copy of bringing an SSN-type ID in India but failed terribly as the Government was more interested using Aadhar to show their domination rather than put it for actual purpose. Eg: Govt made Aadhar mandatory for Tax filing, India's Top Supreme Court denied. The same thing happened in many instances.
This is a nice lesson, why simply coping a solution from the US can't be made to work in a developing nation because the system and officials are so fragile that they need to be first fixed than the solution itself!
