Who pays federal income taxes

Lots of people online are talking about "To Professor@University.edu  Subject: Why It's All About Me".

Apparently, some student e-mails assume an unwarranted familiarity with professors; implied is a lack of respect. Why, the article asks, should students have so little respect for their professors? A faculty member at the Harvard Graduate School of Education is quoted to the effect that students don't respect professors because they realize the professors' "expertise could become rapidly outdated".

I don't buy that at all. Thanks for playing the game, Harvard.

A second explanation offered is "their expertise seems to have become just another service that students, as consumers, are buying."

Bzzzzt.  Better, but sill wrong. And what nice prize do we have for the runner-up, Johnny?

The correct answer is left as an extra credit problem for the reader.
