just like Karen said.. times change a LOT.. I too am a graphic designer..and man do you have to keep updated hehe...

having a non-related job made me rusty on some areas.. but I´m trying to get back on track for when I need it and am ready...

it also depends as you said on demand.. in my country and my original State it was not very much appreciated.. and very much unvalued so they paid miserably for a job as one.. hence I got un-related jobs...
