You are conflating participation from equality, yes everyone participates in the system, it takes a lot of privileged to be able to disassociate ones self from the system itself. The power dynamic within the system favors the wealthy, whom have decided that this is the path we are going down.

But there's always someone richer to complain about.
When someone says "the wealthy" are getting rich to everyone's detriment, they are almost never talking about the doctor who lives three doors down the street from you who drives a nice new 911 or the guy who owns 20 laundromats in your city. I think we all know who we're talking about.
