Back in the 1980s I was working for a major bank in NYC. I was leading a development team that built a wire transfer system to send money anywhere in the world. Customers could dial-n, log into the system and access their accounts to send money t0 over 125 countries. The system was hacked one day and the hackers were wiring money to banks all over the US. Working with federal authorities we identified the hackers who were located in 5 different countries. It took about a month to find them. The difficulty of finding hackers in 5 countries is 100 times more complex than finding someone withdrawing money or cashing checks in a US bank. It is inconceivable to me that DOGE identified 20 million fraudulent Social Security accounts and after a month or more they have not identified and arrested a single person stealing the money.
The process is so simple it should take no longer than 1 day. SS knows where the money is sent. If it is by check, there is an address. Someone has to physically take possession of the check and then take it someplace to cash it. If it is direct deposit, it could get just a bit more complicated nut still pretty easy to find out what is happening to the money.
The fact that no one has been identified and arrested leads me to believe that DOGE jumped the gun on their announcements. What they found m ight just be data quality issues and not fraud. It really is time for them to put up or shut up.
