<p>Since the 70’s the trend in faculty hiring is overwhelming to hire part time adjunct professors. I believe they make up more than half of the overall higher ed teaching staff. That’s an approach that has saved colleges huge amounts of money and provided tremendous scheduling flexibility. I doubt faculty salaries are the driving force for the college cost financial “bubble”. I don’t really think it’s a bubble anyway.</p>
<p>Perhaps we should also consider that salaries for middle class and lower income workers have been stagnant for many years. Had they been increasing even at the rate of inflation, we might not be having this discussion. College, especially a state flag, is a very good deal for wealthier families. Many of whom pay more to go to a private high school.</p>
