I believe some of these honours have been demeaned. Who was that guy who did the insurance advert who refused his OBE because they were also issued to cleaners. And that poet who refused his MBE it because it had overtones of the British Empire in its award. So does your question mean anything anymore?
Well aren't most of them attained by financial means nowadays? So I guess they are effectively worthless in the sense of achievement, but valuable if you have political and commercial motivation.
