99% 

A term used by the occupy wall street protesting the bankers who are considered the 1%, the super rich. 99% refers to the struggling working class. Oddly only bankers and a few CEOs are considered the bad 1%. No one protest celebrities that often make hundreds of times more than their camera man, assistants, writers or a person selling beer at sporting events. Some may argue they have little effect on the common man but when Leno and Letterman make over 35 million a year (despite low ratings) advertisers or the network have to pay more. The workers will get less, more work, let go or outsourced.

Example of those super rich in 1% no one wants protest:
Michael Jordan, Jerry Seinfeld, Jay Leno, Oprah, 50 cent, Barry Manilow, Katie Couric, Kobe Bryant, Dr. Phil, Dr. House, Jeff Gordon, Sam Waterston, Barbara Walters, IMUS, Adam Sandler, Seth Macfarlane, Tiger Woods, Ted Danson and hundreds more.

Brian Williams said with a sad face "the rich keep getting richer while the 99% make less" but he makes twelve million year reading a teleprompter. More than most bankers for working 22 minutes a day. Comes out to about 100k a night. His assistant is likely in the 99%.

Dr. Phil spent 500k on his son's wedding. Then put an ad out needing a assistant from the 99%. Pay? 8 dollars an hour.

99% 

Symbolically the 99% of the population that does not include the super rich 1% (that controls a larger and larger proportion of the wealth, and extraordinary powers in influencing elections).

Since the 1% started to conserve the trickle of wealth downward, the bottom of the bottom 99% have had learn to live without housing, medical and food. Many of the 99% have been forced to live on the street. Wall Street has become the Skit Road of the Great Recession.
