Everyone would receive an equal ration of goods and services, which would be equal to their ability to physically consume such. This means each person would be able to consume as much of whatever they wanted, although they would no longer be able to own whatever they wanted. It also means that the profit incentive would be eliminated. Although people wouldn't be able to own an unlimited number of things, anything that they were using for a sufficient amount of time would be considered "personal items". This would include things like your house or your clothing, but not things like your car, which sits parked for 95% of the time as a result of it being privately owned. Anything not considered "personal items" would be free for anyone to use.
Everyone would contribute an equal share of time and energy in operating society. How is this accomplished? Education would be free and mandatory, including college. The economy would be steady-state, so we would know in advance what % of the population to train for a particular field. The number of students admitted into a particular field would be determined by society's need for particular kinds of work and the student's qualifications (test scores, experience, recommendations, etc).
All the "dirty work" would be automated to the degree possible or eliminated through improved efficiency. Any remaining dirty work would be equally divided among the whole population.
If someone refused to work, their "distribution card" would be deactivated and they could no longer obtain any goods or services. Those unable to work as the result of a disability would be completely cared for and would suffer no loss of income.
Each Industry will be managed by a meritocratic hierarchy of worker volunteers. As someone displayed extraordinary talent or ability, they would be promoted. It's easier to explain by example: Let's say we have three levels, A,B, and C, with A being the highest. A position becomes vacated in level B. Those in level C now become eligible for promotion. To determine who is promoted, those in level C would vote among themselves to determine candidates for promotion. Those in level A would then vote on which of these candidates will take the job. The levels themselves are based on accumulated knowledge and experience required by the job. Level A would require more training than level B, which would require more training than level C, etc. Those in level A make the final decision because they are familiar with the job requirements for level B, having already passed through that position. However, those in level A cannot choose a candidate that is in disagreement with the desires of those in level C, because those in level C determine who the candidates will be in the first place. Multiple-runoff voting would be used for this process.
The job of each Industry would be to provide their goods and services at the lowest possible cost, in terms of labor, resources, and extraneous energy. They would have no reason to do anything other than fulfill this mandate, because the profit motive is non-existent in this system.
The heads of each Industry would form an executive council which would be responsible for long-term national planning. They would vote among themselves to choose a "speaker of the house" whose job it would be to make sure that the agreed upon agenda was being followed. This could be a rotating position.
To remove anyone from their position, a 2/3rd recall vote of the people who work with that person (come into personal contact with them regularly in the workplace) is sufficient.
