Can we, as a society, just stop equating rich and/or famous with important and/or expert?
If someone who got rich by writing a book series that was hugely successful opines on books or being rich, okay, fine. But if he has opinions about other people's sex lives or health or something? Ignore him as the crackpot he is. His opinion doesn't matter any more than any other one person. Stop printing it. He's not an expert on these subjects, he's not important, stop.
