Instead of buying things with money and being paid for work, workers would be given cards (like Drivers' Licenses) that allow them an amount of food and luxuries. In order to ensure that people do all the jobs that need to be done, a sliding pay scale would exist. Job categories would be ranked in importance by periodic votes, and ranked in terms of positions filled by computer (if there are not enough farmers practicing, the ranking for farmers would go up). Votes to determine importance of jobs would be done by occupations as wholes (farming would get one vote, clerks would get on vote, etc. in order to prevent jobs with the most people from voting themselves most important) In this system, the most important jobs that have the lowest worker-to-necessary-worker ratio would get 50% more luxury entitlements than people with the least-important, most-practiced jobs. Every worker would get the same amount of food, based on number of dependents. People who could not work due to temporary or permanent disability would be given a special card that allows food, and fewer luxuries than full-time workers, and would need to be renewed periodically, to be sure that holders actually cannot work. People who have lost their jobs would be issued a temporary unemployment card that allows them food and few luxuries while they look for a job. They must demonstrate that they have been looking for a job to the best of their ability to keep their card. Students would be allowed food and the smallest amount of luxuries, and their education would be free. Standards for workers would be determined by popular vote.
While each country would only be county-sized so that it can do what is best for itself, all the countries would be part of a United Nations style meeting that mediates to prevent war and puts regulations across all the countries.
So, what do y'all think the best way is? Please be wordy.
