Then you can see where they've ever lived, and who with. All for free
It is very right, because social security numbers are not meant to be a secret.
What is wrong is being liable for a debt (or whatever) because a creditor failed to properly verify the identity of a borrower.
Those whole situation can be easily fixed by removing the ability of lenders and governments to claim they verified identity by simply asking for SSN/date if birth.
We have pocket computers with video cameras that can record and transmit spoken agreements within seconds, and we have a nationwide network of USPS offices that already do in person identity verification for issuing passports. Executing the solution is basically done, all that is left is political.
You're never liable for a debt you didn't sign for. If someone else used your information, don't pay it. The court will always side with you.
Also, credit and credit reporting is utility/infrastructure with how life is lived, including access to a place to live. So much that the federal government obligated credit reporting agencies to provide people an annual report. Having to spend time and money to fix it is also a liability, in my opinion.
I certainly don't see my tax returns that way.. is that a commonly held view?
