My Universal Data Base Theory,
A phone directory with a percentage of the population has marginal benefits, but a universal directory with every phone number of the population is exponentially more useful.
If the government asks, voluntarily for every person to fill out a profile then the entrepreneurs will have a far easier time satisfying the needs of their neighbors. It is one thing to be an expert in making shoes, but its an entirely more difficult proposition to know how many shoes, what kind and what size and what demand their will be. However with universal database these most difficult questions for a capitalist shoe making operation become immediately trivial with a universal database which is uniform and backed by and participated in by the society. One simply queries the database to find the demand for shoes, offers to fill the demand locally, shows they have the resources, gets a thumbs up from the local advisory board. This enterprise can even add full lifecycle, recycling, and handme downs to pass the used or refurbished shoes to the next person/child in the database as eveyone is listed. Eventually even the shoe creation projection for years to come can be predetermined.
Another example, perhaps more urgent. I am hungry! This is a button on the phone, no one starves, we know your location and your needs and the first order of business means no one goes hungry. Whether their are euros, drachmas, or not makes no difference. When the farmer brings in xyz amount it it listed in the universal database.
Conclusion: What do you call such a system? Communism? No, Socialism, perhaps, Super efficient capitalism? Perhaps it depends on labor and rewards. How much does the shoemaker get paid? How much does the shoe designer get paid? How much does the engineer that develops a better design get paid? Well we know with universal database we could track exactly how many hours each person involved put in. We could divide equally. If desired we could even simply institute a virtual currency based on hours, one hour is one unit. If the system was more efficient than current neo liberal economic systems than no one would have to spend or acquire more than 40 unit/hours per week. With the universal database, the systems capacity, employment, standard of living, can all be measured instantly at any moment. Any idle resource is cataloged and awaiting an entrepreneur.
Requirements: Near universal usage, thus government endorsement. A temporary tax holiday for all transactions conducted through the system. The seed money to pay programmers to build the initial system. A regulation free zone temporarily, with a vague protection clause, such as if you use the database to exploit your neighbors in such a way that they are upset and feel cheated you will be subject to punishment to community service and in extreme cases jail. The government need to back and enforce a unique id for each phone assigned to each person. They should provide unlimited internet to each person. They should mandate a sort of census, whereby youth that are creating the system go out and teach everyone to input their data to increase the systems value.
Privacy: I have some ideas on how to create nearly perfect privacy standards, I will not expose the details here but should not be too hard.
