I must be f##ked up...
...because I identified with Sean Penn's character completely. The whole movie is about conformity. People are expected to do things a certain way and it's never questioned. There are people on top who get there by being ass-holes and there are people on the bottom who are never allowed to rise above their current circumstances. Bicke didn't want to conform to the expectations of his job (being dishonest, sacrificing his mustache, a symbol of his individuality), even though everyone around him was doing the same thing (the wife whoring herself out as a waitress, his friend resigning himself to his situation because of his race). I identified so much with his anger, especially the line about slavery not really ending; they just call it "employees" now. That's the sort of thing I've been resisting my whole life. If he's "crazy" for rebelling against the system like that, then I guess that makes me crazy, too.
Now obviously my sympathy to the main character ends at the moment he hatches his half-baked plan to assassinate the president (at the moment he shot the dog, I stopped empathizing completely), but I still understand his motives intrinsically. He was unemployed, without any prospect of starting his own business or getting anywhere in life (like the case of the loan office stringing him alone with hope as his application was put through the "system," even though it was obvious the banker never intended on passing it), his marriage and relationship to his kids had dissolved completely, and people generally treated him like he was a creep. Is it his fault he was fed this bull$hit about the American dream all his life? Was it his fault he expected greater things in his life and, barring that, decided to find another way to make his "mark" on the world? It's sad...tragic, even. This is the world we live in.
