Hmmm...
Can anyone come up with examples where a businessman or corporation is the good guy?
Ok, that's somewhat tougher. There are some movies where newspapers are depicted as "good citizens," or reasonable citizens, in any case. That's usually because of the reporters, though, not the suits.
There's the "evil/greedy businessman sees the evil/greediness of his ways" motif. That's kind of a slap in the face, though, saying they can't be a good guy until they change.
I admit, if you have to enlist Google (which I haven't yet) such shows must be rare.
