So I'm going to take this as a serious question.
OK, I'm an information system guy.
So a "person" is an entity - unique "parent" record. That entity has various characteristics such as name, SSN, date of birth, date of death, etc. There there are child records, for example earnings reports received over the persons career.
You NEVER really delete information from a database like this. You WANT the old data because it's used for more than just paying benefits. There may be challenges to benefit awards from an estate, the data is useful for research, etc.
What happened is that Musk focused one field "Death Flag set to FALSE" and he and Trump have spun this into:
Death Flag set to FALSE means paying benefits. This is false.
Death Flag set to False != Receiving Benefits (Spoken, that logic would read "Death flag set to false DOES NOT mean receiving benefits".
A payment issued (for example December 2024 when SS Retirement payments equaled 89,106) means "receiving benefits".
There are not millions and millions of people over 100 receiving SS Retirement. Just ain't happening.
