re: the "existence in society" making up for paying full fees at a T3/T4.
A full-fee T3/T4 graduate's "existence in society" post-graduation will be hustling to find a job. Many will not find employment as lawyers. All will either be (1) rich and have no debt or (2) seriously in debt.
Having experience as a student at a T3 on scholarship, I would not advise anyone who is anything other than 1000%% committed to the practice of law in the face of serious adversity (finding a legal job in a bad economy from a bad school) to pay full tuition at a low-ranking law school.
I agree with most of this. I'm a 1L at NYLS, and a lot of people entered at the beginning of the year thinking that they would be handed a briefcase full of cash just for showing up. (This despite the dean's blunt point at the beginning of the year - that 90% of the class won't be top 10%.) After the first semester grades, I can honestly say that the kids who spent all their time in the library, and actually ENJOYED the day to day experience of learning about the law, did well. The over-confident and lazy bombed, even the bright ones. Don't get into it for the money, because there aren't any guarantees at a school like NYLS.
