“What is one thing every US Citizen has, which separates us from non-US citizens? A Social Security Number.”
Not true, legal immigrants who have work authorization but have not yet become citizens DO have a social security number and are eligible for social security payments when they get to the eligible age.
There is also the option to get a TIN - Taxpayer Identification Number (IIRC) in lieu of a Social Security Number.
But what is going to kill SS is when this government or any leftist government to come legitimizes the ‘migrants’ and they find out they can hold their vote hostage for being grandfathered into Social Security. Instant bankruptcy and insanity.
Actually they apply for TIN "Taxpayer Identification Number" or at least it was that way but before Biden, but who knows now. You have Cities now voting to allow illegals to vote in their elections and apparently they can do that if they want to.
Over 50 years ago all this fraud was quietly approved by the Supreme Court when they ruled residency requirements were unconstitutional. That was aimed at cities that required you to be a registered to vote for a period of time that it was aimed at. What it allowed was college campus students to move into a dorm and potentially dominate an election because they campus population in some cities was nearly as great as the local voter base.
