Excellent node. ++Petras.... I just have one nit to pick. :)

I don't quite get why someone mainly in it for the money is a realist. Is a paycheck the only thing that matters as 'real'? I doubt many people here would agree to that statement, but that's what I infer from your label. Perhaps I'm putting far more thought into it than I should, but it's something I feel I should bring up.
