Well, the society may have started as a joke, but it ended up with over 31,000 members including King George V and George Herman "Babe" Ruth. An initiative of the society was to put a card in each sleeping car with the actual name of the porter on it. This brought a degree of dignity to the job and the person.

Unfortunately, the position of porter and/or bellhop is fast disappearing, mainly since Bernard Sadow put wheels on suitcases. As an aside, our national railway has just eliminated the position of Porter. Over a thousand people are now out of work. Ironically we have an airline called Porter, hopefully they still have Skycaps!
I can't think of other occupations that have this "nominal" stigma. I know that we often refer to menial occupations as "Joe" jobs. Actually, now, I think that they are call "McJobs." Please post if you know of any.
Have an inspiring day!!
