Do you pay lady Gaga to look at her on telescreen?
I think you don't. But you have to watch her singing (personally, she's alright, but she's also part of the system).They are not selling themselves, they are mass culture, and mass culture is propaganda. They make people believe that they have to like them. This is NOT a fair market - this is kinda network marketing.
So they got more than they deserve. This is law. But is it so bad? This is another question.
