Advantages of education with freedom over indoctrination

The eduction in a free country has many advantages over the education under a totalitarian regime.

1. Education is a service.   Just like other services, free competition based on merits produces high-quality services.  The education under the strict control of a totalitarian regime promotes mediocracy, poor allocation of resources.
2. Academic freedom is essential for ideas to flourish.  It allows students to have a wide selection of winning theories, platforms, systems based on free competition.  A totalitarian regime may dictate the indoctrination of their preferred ideas that cannot stand free competition, so their students may waste time on studying counterproductive materials that do more harm than good.   
3. Academic freedom nurtures independent critical thinking that is essential for students to develop into an innovative and productive professional.  Education under a totalitarian regime emphasizes authorities and discourages students from independent and critical thinkings at least on some subjects. Some may argue that students under totalitarian regimes enjoy freedom science and technology.   In reality, it is impossible to have two completely independent parts of a brain that have conflicting modes of thinking.  People indoctrinated by totalitarian regimes often show shared signs of mental impairment.  They may be rigorous and logical at a moment and completely illogical at another moment.  
4. Free speech keeps corruption in check.  The corruption and mediocracy under a totalitarian regime are ubiquitous, and education institutions are no exceptions.  Merits usually are not the major factors for climbing the academic ladder.  The abuse of students by academics is rampant.
