We did. Even in a hierarchy, an executive's primary role is to build consensus, but in a co-op you're contending with increased ego from the participants. In a hierarchy, not being the executive makes it easier to back down on an issue. In a co-op, part of your mind must see yourself as an owner. In a co-op, every active employee needs at least some degree of CEO-ness. And then you have too many CEOs in the boardroom.

Despite my failed attempt at one, I completely agree. To me, the co-op must be the way forward. It's the only likely contender I've found that might bridge capitalism and socialism.
