Unfortunately, meetup.com, forums and Facebook groups wouldn't work so well in Ukraine, because not so many people have computers and internet connection, and even fewer have smartphones. This is why a public forum is a better option, because it will make people turn up there physically. In Ukraine, real world communities work better than online ones. Online forums and Facebook groups are not really taken seriously, even by some young people. Communist Party of Ukraine exists because people participate in it in real life rather than on the internet, even though it's by far not the best community. Being a part of something *physically* rather than virtually means a lot to people of Ukraine. After all, I lived in Ukraine myself, and I visit it every summer.
I have expanded both ideas, and connected them too. If there are still some further questions, I will re-think the defective parts of the ideas. As for connecting them together, it is too early to establish exact way to do it, because we will need to try out all the points that were mentioned in the idea and test them first.
I would extend this idea to a new concept : "contributionalism" - an economy based on meeting human goals rather than meeting growth targets and "making money". People would have an access to a global economic dashboard of wants and needs. Then, they can choose which one they could take on. Even if there is an advent of automation, there will still be a set of tasks that only humans can carry out, such as minding other peoples' animals, children, etc. And also, a human needs to tell robots what to do in order to avoid some bias that come out of perfect algorithmization and automation. If robots will serve humans, then humans will need to tell them what they want. So a dashboard could contain a set of things that a person wants, and a set of tasks that one needs to do in order to get them. Suppose there is a goal or need that is not sufficiently met among a large number of people, then one should get a warning in the dashboard. Then, one will be encouraged to contribute to it if they have the necessary skills for it.
