It's a broken system as is our immigration system. Only goin back and starting all over will we ever get a handle on it. I'm willing for our fed govt. to pay the expense but I doubt the majority of Americans will.
While true, I'd be anxious to get those who have contentious numbers "together" to sort out the discrepancies among them. Then, should the one who has stolen another's be found guilty, they should have all assets confiscated which were acquired over the period of time since they first used the stolen number, incarcerated for a minimum ten years, and lose all rights to citizenship and access to any taxpayer funded services - permanently.
