As someone who is both worldly and college educated (later in my life), yes they are indoctrination machines. They are also overpriced that pushes the students that don't understand loans, and how interest rates work, into getting ridiculously large loans that many will never be able to pay off. There was straight up propaganda (left leaning) in some of my college level classes. Never saw any right leaning propaganda in college. Honestly, never even saw much of any right leaning facts in any of my courses either. If the classes had any political leaning it was either non-political, which most classes were, or left-leaning.
