You also are an idiot.
What some morons don’t seem to realize is that the United States has somewhere around 2,000 four-year colleges and universities, and the vast majority of those don’t have Harvard-style teaching loads. There are hundreds of places where even tenured professors have what is called a 4-4 teaching load (4 courses per semester), and are also supposed to produce something in the way or research and/or publications.
In many of these colleges, there is simply no such thing as a TA. My wife is tenure-track faculty in the Cal State system, and they have no TAs to rely on when teaching their courses. The professors not only teach all their own classes, they do all their own grading as well.
When you are teaching 3 or 4 classes a semester, and doing all your own prep and grading, the teaching alone is easily a 40-hour-a-week job, usually more. This is the case in the humanities, anyway, where grading essays for a class of 50 or 100 students can literally take days if you want to do it properly, with proper feedback on their work. And none of that even touches on the service requirements (faculty committees, job search committees, student advising, etc.) that academics have to do, nor on the fact that if you actually want to get tenure, you need to produce some peer-reviewed articles or a scholarly monograph or two.
And for all of this you go to college for four years, getting pretty much straight A’s all along the way, and then spend anywhere from 4-7 years getting your PhD, to be rewarded in most cases with a salary in the princely range of $40,000 - $60,000 for an Assistant Professor.
Yes, the profs at the top 50 or so research universities have it pretty damn good, as far as teaching goes. But some of these folks also put out multiple field-changing articles and books over the course of their career. And there are literally thousands of professors, at all levels from Assistant Prof through to full Professor, who get by with high teaching loads, modest salaries, and the same sort of constant productivity pressures that you would get in some mid-level business job.
I’m not arguing that it’s the worst job in the world. It clearly isn’t, and it has a lot of rewards. But many of the traditional benefits of being a prof (getting to teach what you want; determining the direction of your own research; spending your summers doing work on things you love; setting your own hours) are being gradually undermined by the demands of teaching, and by budget cuts that pay professors less and expect them to do more.
As i said earlier, the Cal State and UC systems have just cut faculty and staff salaries across the board, have jacked up tuition, and are currently contemplating increasing teaching loads even further next semester. And it’s not just California, and it’s not just public universities.
