Is social security number in US being misused? Developed countries would already have a unique ID in place.

Also, middlemen will not be able to take advantage of this. They will be cut out completely when the person has to avail the benefits after identifying himself/herself.

SSN took at least 150 years to implement and there is substantial difference between the American and Indian situation. Middlemen are already there isn't it? - Technical services companies like TCS, Infosys etc. who are getting paid in billions for something that Facebook/mobile type of platform could also implement at a much lower cost.

I really don't really see your argument. Can you explain a little more?
