As a father of an RU freshman who is paying the bills and will probably have to pay more due to this strike, I get rutrack's position on pay, as these adjuncts have been relied on more and more by the university, essentially taking the place of full time professors. And as somebody who wants a good education for my daughter, I don't want anybody who would work for min wage and live in poverty teaching higher education classes, because basic economics would dictate that these might not be the most highly sought after talent.
As for rutrack himself he's a great guy who understands the subject, he's not attacking high school teachers only using them for comparison.
