I would take economics lessons from Father Jonathan. He's got a good perspective and really knows how to keep an audience's attention. I appreciated the occasional mentions of the students' reactions; they kept the whole thing from being a straight-up monologue.

As for crit, I'm assuming Father Jonathan hews closer to a micro view: it fits with his emphasis on the little details of life and his advice to focus on changing your world instead of the world. I think I'd have liked that to be more explicit, if only to tie up that tiny loose end where he brought up "macro" and "micro" and then only detailed the "macro" worldview. On a somewhat related note, the economic terms he dropped throughout his speech were a nice touch too.

Good words!
