What is one argument against making university-level education free for all students?

One significant argument against making university-level education free for all students is the potential for over-qualification and unemployment. When education is accessible without cost, more individuals may pursue advanced degrees regardless of the actual demand for jobs requiring such qualifications. This can result in a situation where there are more graduates with higher degrees than available positions in their fields, leading to a saturation of the job market. Consequently, individuals may find themselves unable to secure employment that matches their level of education, which can result in underemployment or unemployment. This concern highlights the imbalance that can occur when higher education becomes universally free, potentially diminishing the perceived value of degrees in the job market and affecting overall economic stability.
