You hand-wave this away with "This has been known for decades"… Well, why does it take an unelected South African to step up and fix it?
The reality is that just because something has been “known for decades” doesn’t mean it has been addressed—especially in government bureaucracies, where inefficiency, inertia, and misaligned incentives often prevent meaningful reform. The persistence of outdated Social Security records, massive waste, and fraud is a perfect example of systemic dysfunction.
The president, as the chief executive, has broad authority to ensure that executive agencies function efficiently and effectively. While there are statutory and congressional constraints, the executive branch is ultimately responsible for implementing policies and running departments. If existing bureaucrats and Treasury officials have had access to this data for years but failed to act, then it is not only within the president’s prerogative but arguably his duty to bring in outside expertise—whether that be Musk or anyone else—to tackle waste and inefficiency.
