In a large intro lecture class of 100-200-300 students, there would be no discussion sections without the TAs. A single professor could not handle the load without the TAs.

<p>Maybe I'm just simple-minded. But, for $40,000 a year, shouldn't a student expect the college to hire enough professors to reduce class sizes such that the professor could conduct discussion sections, provide feedback on papers, hold office hours, and generally do the stuff associated with teaching undergrads?</p>
