CMV: Universities should have professors dedicated to teaching only

It seems more and more frequently students are struggling with professors teaching poorly despite ever increasing tuition costs, the pandemic and online learning has only emphasized this. 

It would make sense to me for universities to hire professors that only teach and do not have other responsibilities such as research etc. This would allow them to focus solely on teaching, providing the best learning experience for their students. Additionally they can have an increased amount of office hours. 

This may also mean that they can teach multiple classes so students become used to them and they can relate various classes together (if applicable). Especially for undergrad, you may not even require professors and instead use lecturers (those without doctorates) to teach as the course information is usually not on the cutting edge of the subject and instead is well-planted in history and well known (for example calculus). 

As an engineering student, I've had some good profs, one excellent out of this world amazing prof and a bunch that were difficult to learn from. It seems I am not alone in these appraisals.

Thoughts?

Sounds like what you want is to attend a community college.

What attracts people to programs at university is the prospect of working with researchers in their field of choice.  And there just isn't enough work/money to give a very specialized professor ONLY responsibilities of teaching his/her own specialty and research.  So each specialist also takes some general classes to help justify their role/salary at the university, since their specialist classes may just be a handful of students.

So the current University approach:

* Makes sure the university has as many different researchers as it can afford to
* Gives the researchers a better work environment because of the plentiful amount of potential collaborators both in their discipline and across disciplines
* Supports an important University mission which is to push research forward
* Exposes younger students to these researchers
* Gives their students the widest range of options in terms of specializations

Your system would not allow the university to afford a larger staff.  You'd be replacing specialized researchers with non-researchers.  This is a drag on several important goals of the university from pushing forward research to attracting new students with their researchers.
