The adjunct instructors and graduate assistants you had were people working very hard to secure full time employment elsewhere. That is why they were so good. However, how do your propose that they make enough money to pay their bills, save for their students college fund, perhaps dream of buying a house, have health insurance, etc. Eventually, if there are no full time teaching positions, they will have to seek some other employment as oppossed to an entire life making about $25,000 a year. I have no problem with having several different tiers of instructors .. those who primarily teach, those who research, some who are part time ... the very young and the very old. But would you try to run a corporation with everyone working part time, no benefits, etc? Wait, I guess many here see the world operating this way.
