> Faculty must be allowed to do research 90 % of the time
God no. This is exactly the problem that most undergraduate campuses in the US are grappling with right now. Pedagogy (you know, the purported reason for the existence of universities when they were first established) is taking a backseat to research, with students not deriving nearly the value from college that they should be. Most newly-minted PhD candidates want to create rigorous research programs, even at small liberal arts colleges, much to the detriment of those who matriculate (and who consequently accumulate ludicrous amounts of debt).
It would be much better for academia to have an honest conversation with itself and note that some people want to teach while others want to do research, and send the research-inclined to non-teaching institutes like IAS, LLNL, the Broad Institute, etc and the teaching-inclined to work with undergraduates. The outliers who fall in the middle of the Venn diagram can choose for themselves which direction they want to go.
It also would help if workshops to develop pedagogical techniques weren't almost universally optional for grad students and the ones who do engage in them get looks for wanting to do them instead of doing research... this may be just an impression on my part, but I really felt like grad students I've encountered who prioritize teaching over publications get marginalized.
