The entire nationalizing of the student loan program was a long con (as part of the Affordable Care Act no less!). It originated with a message of, "We'll save costs by cutting out the middle men!". That was a complete charade as the goal from day one was to take control of the debt so that it could be selectively discharged.
Thankfully Trump's 2016 win has cemented a conservative SCOTUS for the near future and they put a stop to this nonsense. Regardless of the outcome of 2024, that's going to his most lasting impact on the country.
