Dumb Bumper Stickers

Why are so many people so proud of being part of "the 99 percent"? You're driving a mini-van in my neighborhood; I could have guessed that you're part of the 99 percent. I would be proud to be part of the 1 percent....why is it such a bad thing that people have to say they're part of the majority. I'm just waiting to see a bumper sticker that says they're part of the 1 percent. That would be funny, as opposed to just obvious.
