Man, japanese people really go all out on everything, even at being a good for nothing!
Or maybe that's what the author wants for his characters... I think there's not a single one like that, if they are so thoughtful as to think of what they do as a way of life, doing it because "they can do what they want", as that wrestler said, they'd be out of it sooner than later. As it's evident they can't do that much.
