I think the problem with Communism and Capitalism, is that both were implemented in the first place without specific goals or structure. Those things got added on later, such as the 5 year plans or how lobbying works.
IMO, we will need a v2.0 Constitution in the future, designed not only to address political issues, but also create fiscal rules. Things like universal benefits and healthcare, how much people should be payed, wealth limits, workers voting for their leadership, and so on. This, like the Magna Carta or the French Revolution, will require force in order to displace the ways of old.
It will suck, but conflict seems inevitable. Might as well make the most of it, and forge a new way forward.
I have been trying to put together a document that attempt this concept of ensuring the survival of people, while making money into something used for lifestyle upgrades. Also, heavy emphasis on wealth limits and preferring people over corporations. IMO, corporations are great for personal interests, but are beyond terrible when it comes to the wellbeing of people. Thus, we should make having a job optional, but rewarding.
