Capital is human labor, which is the source of all that is produced. It can function without money, but that requires a much more evolved, high-tech humanity, which I don't believe exists today or will exist for a long time. Human Star Trek economy and society won't be around for a while. Until then we need a well-regulated capitalism, serving the country, under a national socialist government. There will be no UBI checks, no worthless consumer serfs, no robots and artificial intelligence replacing all human labor, nor will there ever be Marxist communism or techno-feudalism.
National socialism, which respects both personal and private property is the solution, one that allows for everyone to keep their jobs and businesses intact, serving the community. There's a place for the working class and a place in society for the wealthy as well.
