A natural equilibrium of institutions doesn’t have to leave anyone better off. Excellence at research is the most legible prestige-carrying property of professors, being good teachers is harder to observe. As Viliam points out, the purpose of raising researchers is best served by teachers who are good researchers, and also otherwise there is risk of content drifting away from relevance or sanity. So even for students, orgs with good researchers are more credible sources of learning, given the current state of legible education quality indicators.
