This is a very good point. Some University professors get into it for research, some for teaching, not many for both. The problem is that Universities will typically cater to one type of professor, leaving the others scrambling to spend a lot of time doing the thing that they don't like (and which takes a lot of their time). Also, Teaching Assistants really should be offered more in every level of education. A good TA can reduce the instructor's load significantly, while at the same time offering much better interaction ratios with students with questions.
