Fame is all about context though. I'm reminded of a specific incident when Kanye was leaving a taxi in France, and bumped into some woman. They had a short conversation and she walked away. Paparazzi asked her if she knew who he was, she said "no," they said "that's Kanye West!" She said "who's Kanye West?"
Similarly, I wouldn't recognize the president of Brazil. Or the senators of Idaho... Or the governor of new York...
