I'm sure anyone wherever they may be who applies to go on the show are searching for some level of fame in the first place.
And should they grab a few quid after the show .. fair play to them I say.
My personal interest in them only extends to the time they were actually in the show though.
Italian BB is the same. in fact most of them chosen look like models and want TV careers. At least BBUK put the odd older hm every year. I can't remember of more than 5 over 40s in 15 years of Grande Fratello
