I agree with you. Keep in mind that Economic Democracy is not supposed to be capitalism. It's post-capitalism. It's really just an exercise in economics-fiction. Every economics framework is vulnerable to corruption.
See: http://en.wikipedia.org/wiki/Post-capitalism
So, it's kind of like imagining what a science-fiction economics framework might look like. For instance Stark Trek economics looks nothing like capitalism.Post-capitalism refers to any hypothetical future economic system that is to supersede capitalism as the dominant form of economic organization.

Capitalism is great if you're lucky enough to succeed. But, it's not so great for the bottom of the barrel. Most post capitalistic frameworks are about giving everyone a fair shot. Capitalism tends to favor the top of the heap.
Anyway, there are many post capitalism systems to choose from."The laws of capitalism, which are blind and are invisible to ordinary people, act upon the individual without he or she being aware of it. One sees only the vastness of a seemingly infinite horizon ahead. That is how it is painted by capitalist propagandists who purport to draw a lesson from the example of Rockefeller — whether or not it is true — about the possibilities of individual success. The amount of poverty and suffering required for a Rockefeller to emerge, and the amount of depravity entailed in the accumulation of a fortune of such magnitude, are left out of the picture, and it is not always possible for the popular forces to expose this clearly.... It is a contest among wolves. One can win only at the cost of the failure of others." — Che Guevara
