Your straightforward question covers both ends of the education system and is at once both easy to answer and challenging.
For example, the Constitution is a contract, and IMO, Contract Law varies only slightly, if at all, from school to school. However, by the time most students reach law school, their worldview and mindset have been formed (sometimes beginning at kindergarten).

And yes, the indoctrination is bad up to—and then even worse in—law school. Law professors are about as bad as it gets.
Moreover, nudgy, authoritarian-type personalities seem to be drawn to the law to start with!
