You're staring in the face of a giant availability bias.
"We are the 99%" is filled with people who can afford a webcam/camera, a computer, and internet access. Some even have gone to college. That's vastly richer than the average human being.
Uh, no that's not what it's saying. It's railing against the top 1% of people that have huge capital. People who have webcams/cameras etc. are contained in the 99% of Americans. They aren't the "average" of the 99%. Each is one of the 99% who do not have huge capital and together they make up the 99%. In other words, in order for you to have a problem with their claims, you need to show that someone who says "We are the 99%" is actually part of the top 1%.
If you prefer, they could say "I am one of the 99%," but that's not as catchy.
