There are professors who teach at community colleges and help students get 2 year degrees.
There are professors who teach undergraduates.
There are professors who teach graduate students who are working on doctorates they will use in industry.
And finally, there are professors who get to mint new professors.
That final list SHOULD be an elite. Academia is done growing, which means if you're a full professor, you should expect exactly one of your advisees to make full professor. Out of the entire career's retinue of advisees. Some professors will get to mint more than that. Others will have zero.
