I'm aware its probably not an accurate portrayal, its just the kind of thing the UK/AU/NZ hears a lot from americans and we don't quite understand the narrow minded logic.
While you're right that the doll bludger should "just get a job", you thinking that isn't going to change the fact that they won't.
As an American, I often fear that responsibility, self-reliance, and self-determinism aren't respected by my countrymen.
So I'm rather heartened to hear that.
