*thoughtful* You know, I think as I've gotten older I've had a lot fewer people I wanted to be like overall, as in 'wow what an amazing person'. I want to write like Bujold and Hambly. I want to teach like Scott Friesner (one of my teachers from undergrad). But none of them is what I'd call a hero to me.
Now, if Obama can actually make the bailed-out ceos swallow $500,000 salaries, he'll kind of be a hero for me, but that's more the hysterical relief of "somebody's doing something, maybe we won't have the French Revolution this week".
I suppose there's Utah Phillips.
