He does. That's what started this thread: he provided evidence and context to back up his claims of widespread government waste and fraud. What that got him was a bunch of smears from people spreading misinformation about COBOL.
Anyone else in the world would just stop sharing stuff publicly given this kind of public abuse. There's no requirement to do so. But Musk just shared evidence and context again, by showing the output of the equivalent of SELECT GROUP(age), COUNT(*) FROM SSNS WHERE DEAD = FALSE:
https://x.com/elonmusk/status/1891350795452654076
It shows approx 1.3 million SSNs in the 150-159 age bucket, along with many millions more that are actually over that age, and over 1000 SSNs allocated to people over 200 years old, including one that is for someone marked as 360-369 years old. There are over 20M people listed as 100+ years old. Total sum is around 395M people. Therefore there is no 1875 epoch and that claim was simply misinformation.
So here's what we know given his statements:
1. There are a lot of data entry errors in the SSN database.
2. These aren't test data, misinterpretations of an epoch, etc.
3. Such errors are extremely common and not being rectified.
4. Many SSNs aren't unique.
5. There are far more records in the database than people in America.
If we combine those statements with prior knowledge of other related topics, we can infer:
• The data quality issues are much more extensive than just age and number of records.
• Whatever processes are meant to ensure data quality don't work.
• This was not previously known to the public.
• Civil servants know all this but are often unable to do anything.
We also know that this situation is expected. It would be much more crazy if Musk announced his team couldn't find fraud in SS. Just look at the graph for payouts from the American disability benefits system - it tracks general economic performance. Other countries don't see such a thing in their payouts, where improving economic conditions magically make long term disabilities disappear, but they also tend to be more aggressive at cracking down on benefits fraud. The UK did a big purge some years ago where every single person claiming disability benefits was re-assessed.
Anytime someone comes in and does basic checks of government finance systems they always find lots of very basic stuff. At one point it was discovered, again in Britain, that a Labour council was regularly paying invoices multiple times and nobody had noticed for years. Paying money out to dead or non-existent people is a common problem in all such systems.
