I’ve wondered the same. But I’ve come to realize that many celebrities really do think they are better than the rest of us - better, smarter, above us, etc.
I’d like to think that if I had ever become a celebrity, I would thank my lucky stars and realize just how lucky I was to hit the celebrity lottery...because lets face it, most of these celebrities are nothing special - just had a lucky break. But who knows, maybe I’d be a fool too.
I'm with you, I'd drop down on my knees and thank God for my good fortune.
