“That which is unaffordable is unsustainable and will go away. The current system of higher education is profoundly unaffordable: it exists on an immoral foundation of student debt–$560 billion of which is Federal. Enormous expansions of student debt are required to keep the current system of higher education afloat. This chart shows the insane trajectory of Federal student debt. But unaffordability is only one reason why the present system of higher education is unsustainable. Despite the good intentions and hard work of individuals, these systems are broken. Due to their size and structure, large systems such as national defense, healthcare and education limit the impact of individual initiative.”
