I was trying to point out how high tuition for universities is. I'm not sure if this is a US-specific problem, so I won't comment on that, but my point was universities receive so much money to conduct research, and then put that very research behind extremely expensive paywalls.

If what you said is correct (which I'm sure it is), it's only reduced my understanding (in a good way - thank you for your explanation). So - the government pays professors for their research, and then this very research is put behind a paywall, from which....publishers (?) make money?. I apologize, but it simply does not make sense to me, it seems extremely counter intuitive.
