I think what really made his reaction so ugly was the absolute disdain he had for Jimmy's schooling. While there may be a difference in prestige in law schools and some are way harder to get in to than others, the reality is that all lawyers take the same classes, pass the same bar, and, realistically, the lower level schools have much more stringent curves and are actually harder to get through than the elite schools (for example, it's waaaaay harder to get into Stanford or Yale than it is into Cooley, but it's waaaaaay harder to pass through Cooley with good grades than it is at Stanford or Yale).
