This problem could be solved with a co-op structure even within a free market. If ten workers in a co op produce $100 bucks of extra money, they all get voting power over ten buck, and as long as any new hires can carry their weight so everyone still gets ten bucks surplus to command, they will hire them if you follow the game theory incentives. Once companies get big enough to have diminishing returns, like a new employee could only produce 5 bucks of surplus, then hiring that person would make everyone have a smaller piece of the pie (adding him to our first ten means the share drops to 105/11 or 9.5 dollars.) If the pie(surplus) all goes to one person they can keep adding workers until the worker doesn’t produce any surplus over the cost, bloating the departments. Because of this co ops tend to expand to peak productivity, (surplus per worker), rather that peak output (produce as much as we can until it becomes unprofitable to produce)
