As a youngster I always assumed somebody on TV was getting paid truck loads of coin. My wife drives a school bus part-time to help make ends meet today. One of her co-workers is a man that had been a production assistant on Kung Fu: The Legend Continues (a fine exercise in camp-fantasy). I remember speaking with him at our last Christmas party. He had been a driver even back then during the show's hiatus and off periods. He explained it was famine....and not quite feast....at the best of times...even for the actors.
My new assumption is outside of a handful of know commodities on the tube, most make far less than people think, OR, their expenses, leased homes and cars...are trapping they have to assume in order to fit in and give the impression of success.
